Facility Electrical Protection

Lightning protection, grounding, equipotential bonding

and surge protection are all interdependent disciplines

and the focus of the ERITECH® brand of facility electrical

protection products. Reliable protection of personnel

and structures demands a systematic and comprehensive

approach to minimizing threats caused by transients

and other system disturbances. For instance, no air

terminal can safely capture and arrest the lightning

energy without a dependable route to ground. Equally,

even the most expensive surge protection device

(SPD) will not provide optimum protection if a low-

impedance electrical connection to the ground is not

present. Additionally, a low-impedance ground system

may create hazards to equipment and personnel

alike if equipotential bonding is not in place. These

interdependent disciplines are best applied when

looking at a total facility rather than an individual piece

of equipment or a portion of the facility.

Since no single technology can eliminate the harmful

effects of lightning or induced-surge transients, ERICO

has developed the Six Point Plan of Protection. The

concept behind this plan is a holistic and coordinated

approach that embraces all aspects of effective facility

electrical protection.

The six interdependent disciplines that form the

protection plan are:

1. Capture the lightning strike

2. Convey this energy to ground

3. Dissipate energy into the grounding system

4. Bond all ground points together

5. Protect incoming AC power feeders

6. Protect low voltage data/telecommunications circuits

At ERICO, we offer innovative, efﬁcient grounding and

bonding products as well as engineering experience

and technical support. With this experience, ERICO is a

world-leading authority in the design and construction of

permanent, low-impedance grounding systems.

ERICO employs a quality-assurance program to help

ensure that detailed procedures required for every step of

the operation produce the best possible system for our

clients. This attention to detail includes design, materials

procurement, manufacturing, installation and testing.

Our research and development capabilities provide

continuous design improvement with new and improved

products that preempt the challenging requirements of

ever-evolving industry applications. Engineering expertise is

shared among the other ERICO operations worldwide, to

provide a comprehensive global knowledge pool.

It is a fundamental fact that electricity ALWAYS flows to

the point of lowest potential. The task is to help ensure that

electricity, including faults, lightning and electronic noise,

flows to this point with maximum safety to people, while

maintaining the reliability of equipment. Therefore we must

help ensure the safe, controlled flow of electricity with

minimum voltage drop to earth in all cases.

Grounding Codes and Standards

Grounding needs vary according to function. The grounding

requirements of a power system will vary from those of

electrical equipment, lightning protection or for the proper

function of electronic equipment.

Proper installation of appropriate grounding systems

requires knowledge of the needs and layout of the

facility. Soil characteristics, grounding conductor materials

grounding connections and terminations, are significant

factors determining the design of a grounding system.

Applicable standards and codes must be applied.

While many codes and standards contain minimum

grounding and bonding requirements, the design and

installation of electrical grounding systems is one of the

most important aspects of any electrical distribution system.

However, codes and standards are often misunderstood and

grounding systems subsequently installed improperly.

Ground: A conducting connection, whether intentional

or accidental, between an electrical circuit or equipment

and the earth, or to some conducting body that serves in

place of the earth.

Earth: The conductive mass of the earth, whose electric

potential at any point is conventionally taken as equal

to zero. (In some countries the term “ground” is used

instead of “earth.”)

There are important reasons why a grounding system

should be installed.

1 The most important reason is to help protect people!

2 To help provide protection of structures and

equipment from unintentional contact with live

conductors.

3 To help support maximum safety from electrical system

faults and lightning.

Bonding: The permanent joining of metallic parts to

form an electrically conductive path that will ensure

electrical continuity and the capacity to conduct any

current likely to be imposed.

Basic Definitions

The need to ground!

GROUNDING PRINCIPLES

Grounding and bonding are an integral part

of any modern electrical protection system

design.

An effective, low-impedance ground system

is a key element of this system. It is crucial

to help provide personnel safety, as well as

reliable protection for vital equipment and to

minimize interruptions of service and costly

downtime.

With over a century of experience in the

design and manufacture of bonding and

grounding products, ERICO, a single source

provider, offers what we believe is the best

range of long lasting and cost-effective

grounding products available.

Soil conditions and seasonal patterns vary

from site to site, the methods of grounding

need to be considered on an individual basis.

TECHNICAL INFORMATION

Why is Good Grounding Important?

The transient nature of lightning with its associated

fast rise times and large magnitude currents mean that

special consideration needs to be given to grounding, for

lightning protection to be effective. Many factors such as

soil resistivity variations, installation accessibility, layout

and existing physical features are all site speciﬁc and tend

to affect decisions on grounding methods employed. The

primary aim of a direct strike grounding system is to:

• Efcientlydissipatelightningenergyintotheground

• Helpprotectequipmentandpersonnel

Grounding Principles

Low impedance is the key to lightning protection. All

grounding connections should be as short and direct

as possible to minimize inductance and reduce peak

voltages induced in the connections. The ground

electrode system must efﬁciently couple lightning surges

into the ground by maximizing capacitive coupling to

the soil. The resistance of the ground itself to lightning

currents must also be minimized. Only when all these

factors are taken into account will maximum lightning

protection be achieved.

Grounding Principles

Ground Impedance

Soil resistivity is an important design consideration. It

varies markedly for different soil types, moisture content

and temperatures and gives rise to variations in ground

impedances.

Short, Direct Ground Connections

The voltage generated by a lightning discharge depends

primarily on the risetime of the current and the

impedance (primarily inductance) of the path to ground.

Extremely fast rise times result in signiﬁcant voltage

rises due to any series inductance resulting from long,

indirect paths, or sharp bends in the routing of ground

conductors. This is why short, direct ground connections

are important.

Coupling from the Electrode System

to the Ground

The efﬁciency of a ground electrode system in coupling

a lightning current to ground is dependent on a number

of factors, including the geometry of the ground

electrode system, the shape of the conductors and the

effective coupling into the soil.

GROUNDING PRINCIPLES

TECHNICAL INFORMATION

Figure 1-B illustrates current ﬂow from the injection

point of a single ground electrode. As current ﬂows out

from the central injection point, a voltage gradient on the

ground surface around the electrode is produced. This

gradient levels off to a plateau at some distance from the

electrode, as seen in Figure 1-A. The impedance seen

by the current is determined by the soil particles in direct

contact with the surface of the rod, and by the general

impedance of the soil.

Characteristics of a Good Grounding System

•Good electrical conductivity

•Conductors capable of withstanding available

electrical fault currents

•Long life — at least 40 years

•Low ground resistance and impedance

The basic philosophy of any grounding installation should

be an attempt to maximize the surface area of electrodes

or conductors with the surrounding soil. Not only does

this help to lower the earth resistance of the grounding

system, but it also greatly improves the impedance of the

grounding system under lightning surge conditions.

•Equipotential bonding

Equipotential bonding helps ensure that hazardous

potential differences do not occur between different

incoming conductors such as metallic water services,

power systems, telecommunication systems and the

local ground, and also minimizes step and touch

potentials.

•Good corrosion resistance

The ground electrode system should be corrosion resistant,

and compatible with other conductors that are buried

and bonded to the ground system. Copper is by far the

most common material used for grounding conductors. In

general, some form of maintenance or inspection procedure

should be adopted to ensure the long-term effectiveness of

a grounding system.

•Electrically and mechanically robust and reliable

Mechanical coupling can be used to join ground conductors,

but suffers from corrosion effects when dissimilar metals

are involved. As well as mechanical strength, CADWELD®

connections provide excellent low impedance, long life

electrical connections with excellent corrosion resistance.

When current flows from a ground electrode into the

surrounding soil, it is often described as flowing through a

series of concentric shells of increasing diameter.

Each successive shell has a greater area for current flow

and consequently, lower resistance. At some point distant

from the earth conductor the current dissipation becomes

so large and current density so small, that the resistance is

negligible.

In theory, the ground resistance may be derived from the

general formula:

R = resistance in ohms of the ground rod to the earth (or soil)

L = grounding electrode length

r = grounding electrode radius

ρ = average resistivity in ohms-cm.

In the case of ground resistance, uniform earth (or soil)

resistivity throughout the volume is assumed, although this

is seldom the case in nature. The equations for systems of

electrodes are very complex and often expressed only as

approximations. The most commonly used formula for single

ground electrode systems, developed by Professor H.R. Dwight

of the Massachusetts Institute of Technology, is the following:

This formula illustrates why the shells of concentric earth

decrease in resistance the farther they are from the ground rod:

Conditions Influencing Soil Resistivity

The resistance of the earth itself (soil resistivity) can

significantly impact the overall impedance of the grounding

system. Several factors, such as soil composition, moisture

content, mineral content, contaminants, etc., determine the

overall resistivity of the earth.

Soil Resistivity Testing

To properly design a grounding system, it is essential to

test soil resistivity. Several methods can he used to measure

earth resistivity: the four-point method, the variation

in-depth method (three-point method) and the two-point

method. The most accurate method and the one that

ERICO recommends is the four-point method.

R = __ {(ln 4L) - 1}

2πL r

Sphere of Influence - electrical current flows from the ground

rod into surrounding soil and progressively dissipates in waves of

increasing diameter.

≤

The Four-Point Method

1. Four test stakes are positioned in a straight line an equal

distance apart and are hammered into the ground to be

surveyed to a depth of not more than 1/20 the distance

between the adjacent stakes.

2. An earth resistance tester is connected to these four

stakes as shown in Figure 2.

3. The DC test option on the tester is then selected and

performed, and the resistance figure “R” recorded.

4. The soil resistivity level “r” (in ohms/cm) is then

calculated using the formula: r=2paR where:

R = the resistance figure, in ohms

a = the separation of the test stakes, in meters.

p = 4πAR

1 + 2A – 2A

√ (A2 + 4B2) √ (A2 + 4B2)

Where:

A = distance between the electrodes in centimeters

B = electrode depth in centimeters

If A > 20 B, the formula becomes:

p = 2π AR (with A in cm)

p = 191.5 AR (with A in feet)

p = Soil resistivity (ohm-cm)

This value is average resistivity of the ground at a depth

equivalent to the distance “A” between two electrodes.

except that the fault current passes through the

Another function of the grounding system is

to provide a reference for circuit conductors to

stabilize their voltage to ground during normal

operation. The earth itself is not essential to

provide a reference function; another suitable

inductive body may be used instead.

The function of a grounding electrode system

and a ground terminal is to provide a system of

conductors, which ensures electrical contact with

the earth.

GROUNDING PRINCIPLES

Grounding / Earthing System Design

Grounding systems are important. It is not expensive

to build an appropriate ground system during initial

construction of a facility, but it can be very expensive to add

to it, enhance it, or replace it after the facility is complete.

Care should be taken to design a system that is appropriate

both for clearing ground faults and dissipating lightning

energy. The system must have a long performance life,

meet applicable codes / standards for safety, and have

sufficient bonding points to make it easy to add new

equipment / facility grounding to it easily.

For proper operation of overcurrent devices, it is important

to have a low DC ohmic resistance to remote earth. In

many instances, this is best achieved by installing a deep

ground electrode on site. It should be driven deep enough

to reach the permanent water table.

For dissipation of direct or indirect lightning currents, it

is better to have many horizontal ground conductors in

the soil, preferably in a radial array. This provides a low

impedance path of dissipation to the high frequency

component of the lightning energy.

For personnel, particularly where people congregate or

where equipment operators will be located, it is important

to have a grid system or other equipotential plane to reduce

“step potential” and have equipment and metal structures

bonded to the ground system to reduce “touch potential”.

Design considerations include:

•Purposeoffacility

•Designlifeoffacility

•Soilresistivityat3depths

•Corrosivenatureofsoil

•Shapeandavailableareaoffacilitysite

•Futureuses,additions,equipmentforfacility

A proper facility grounding system incorporates these

necessities in the most cost-effective manner that will last

for the design life of the facility.

GROUNDING PRINCIPLES

The Grounding Chain

The performance of the grounding system is determined by

the quality of the following five components all of which

are of equal importance.

1. The Grounding Electrode Conductor. Typically made

from copper or copper-bonded steel, the grounding

electrode conductor must be large enough to withstand

the maximum available fault current over the maximum

clearing time.

2. The Grounding Connections. Often overlooked, the

grounding connections are used to tie the elements of

the electrode system together. Exothermically welded

connections provide a molecular bond that will never

loosen or corrode. Mechanical connectors, such as

crimp, bolted, and wedge type, rely on physical point-

to-point surface contact to maintain the integrity of

the electrical connection. IEEE® Standard 837 provides

detailed information on the application and testing of

permanent grounding connections. ERICO can provide

an independent, third-party test report evaluating the

performance of these connectors in accordance with

the testing procedures set forth in IEEE 837 Standard for

Qualifying Permanent Substation Grounding Connections.

3. The Grounding Electrode. The grounding electrode

provides the physical connection to the earth and is the

instrument used to dissipate current into it. There are

two main types of electrodes. “Natural” electrodes are

intrinsic to the facility and include metal underground

water pipe, the metal frame of the building (if effectively

grounded), and reinforcing bar in concrete foundations.

“Made” electrodes are installed specifically to improve

the performance of the ground system and include wire

meshes, metallic plates, buried copper conductor and

rods or pipes driven into the ground. The ground rod is

the most widely used electrode.

4. Electrode to Soil Resistance. Amount of rod surface and

rod replacement are the controlling factors. Doubling

diameter reduces resistance by only 10% and is not cost

effective. Doubling rod length, however, theoretically

reduces resistance by 40%. The most common solution is

proper placement of multiple rods that are driven to the

required depths.

5. The Soil. The soil resistivity, measured in ohm-centimeters

or ohm-meters, plays a significant role in determining

the overall performance of the grounding system and

must be known before a proper grounding system can

be engineered. Measuring soil resistivity allows the design

engineer to locate an area with the most conductive soil

and to determine the depth of the conductive soil so that

electrodes can be placed accordingly.

The grounding system will carry little or no current for long

periods of time until a fault occurs or a lightning strike

or other transient requires dissipation. At that point, the

grounding system components will be expected to perform

like new while conducting large amounts of current.

Most of the grounding system is concealed below grade,

making inspection of the grounding components difficult

or impossible. The underground environment is a harsh

one. The initial selection of the components used in the

grounding system is of critical importance to its long-term

effectiveness.

Ground Electrodes

The ground electrode is a critical component of the grounding system. Many different types of electrodes

are available, some “natural” and some “made”. The natural types include metal underground water

pipe, the metal frame of a building (if effectively grounded), a copper wire or reinforcing bar in a

concrete foundation or underground structures or systems. Consideration should be given

to bonding of natural earths to ensure electrical continuity with a facility’s other “earths”.

“Made” electrodes are specifically installed to improve the system grounding or

earthing. These earth electrodes must ideally penetrate into the moisture

level below the ground level to reduce resistance. They must also consist

of metal conductors (or a combination of metal conductor types), which

do not corrode excessively for the period of time they are expected to serve.

Made electrodes include rods or pipes driven into the earth, metallic plates

buried in the earth or a copper wire ring encircling the structure.

Underground gas piping or aluminum electrodes are NOT permitted for

use as ground electrodes.

Ground Rods -

Which ground rod should be used?

Ground rods are often selected on the basis of their resistance to

corrosion. The other major factor is cost. All too often, the cost of

a product is seen as the initial up front price, but the real cost is

determined by the serviceable life of the ground rod.

Galvanized steel rods are one of the cheapest electrodes

available. However, they are not the most cost effective

since they have a relatively short service life. Solid copper

and stainless steel rods have a long service life. However,

they are considerably more expensive than galvanized steel

rods. In addition to this, solid copper rods are not suited

to deep driving or even driving short lengths into hard

ground, without bending.

Ground System Components

GROUND SYSTEM COMPONENTS

Copper-Bonded Ground Rod

The copper-bonded ground rod has an electrolytic

coating of copper deposited over a layer of nickel. This

process ensures a long lasting, molecular bond between

the copper layer and the steel core. ERICO recommends

copper-bonded ground rods because the copper coating

will not slip or tear when driven, nor will it crack if the

rod is bent. The tough, carbon steel core has good

characteristics for deep driving. Copper-bonded ground

rods have a high resistance to corrosion and provide

a low resistance path to ground.

The Stainless Steel Ground Rod Option

It is important to note that certain soils and land fill areas

may not be compatible with copper. In these situations,

stainless steel is a better proposition. Stainless steel may

also be an alternative, where structures or components,

such as steel towers, poles or lead sheathed cables are

in close proximity to an array of ground electrodes. In

these circumstances, consideration must be given to

the consequence of galvanic corrosion. The high cost of

stainless steel rods prohibits their widespread use.

The photo on the right shows a galvanized steel ground

rod driven vertically into the ground at the Pawnee

testing site in Las Vegas, NV. One area is reduced from a

3/4” diameter to approximately a 1/4” diameter due to

extensive corrosion.

The eventual failure would result in a

potentially catastrophic loss of ground.

NEGRP

The photo on the left shows two ground rods that were

is copper-bonded, 5/8” x 8’. Both ground rods were

exhumed from the site in April of 2004. The loss of zinc

resulted in excessive corrosion of the steel. The copper-

bonded steel ground rods showed minimal corrosion.

Conductors

There are two basic criteria for grounding conductor

selection:

1. The physical characteristics of the conductor must be

of a robust nature, sufficient for the environment.

2. The cross sectional area of the conductor must be of

sufficient size, so that it shall successfully conduct the

maximum fault current for a period, which allows

the operation of protection equipment (or the

dissipation of this energy).

Physical Characteristics

The most common ground conductor is a soft drawn,

stranded copper conductor. Flat copper strip / tape is also

popular because it offers a large surface area, resulting in

lower impedance.

In some circumstances, the maximum fault current for the

installation is small. While a conductor of correspondingly

small size could be used, a minimum cross section, often

set by the governing authority or applicable standards

body (to minimize potential damage likely to occur from

any future excavation on the site), is applied.

Maximum Fault Current

Where higher fault conditions exist, the conductor size

is determined by considering the circumstances required

to avoid fusing (melting) the conductor. The accepted

industry standard is IEEE® 80, Guide for Safety in

Substation Grounding.

GROUNDING SYSTEM COMPONENTS

Ground Electrodes

Ground Rod Accessories and Application

ERICO, a leading manufacturer of UL® listed copper-

bonded ground rods, offers a complete range of

rods, driving sleeves and studs, rod coupling methods

and connections for reliable grounding in nearly any

application.

Driving Sleeves

The driving sleeve

fits over the

pointed ground

rod to protect

the rod end from

“mushrooming” as

the ground rod

is driven into earth.

Compression

Coupling

Couplings enable

ground rods to

be driven quickly

and easily without

the risk of rod

separation. They are

generally tapered so

when the rod is driven

into the coupling, the two

parts compress to form

a conductive connection.

Threaded

Coupling

Threaded couplings

allow for full contact

of the rod point

with the butt end of

the preceding rod.

Ground

Rods

Ground Rod

Diameter and

Length

Ground rod

diameter

must also be

considered.

Although larger

diameter rods

are more rigid

and less prone to whip or bending, they may have a

greater drag than smaller diameter rods when being

driven. It must also be noted that increasing the ground

rod diameter has relatively small impact on grounding

system resistance when compared to length. Standards

nominate a minimum diameter or periphery and thickness

if not cylindrical, mainly based on mechanical strength.

In general, lightning protection standards recommend

copper-bonded electrodes of specified diameter. Standard

UL 467 requires a minimum rod length of 8’ with a

minimum diameter of 0.50” and 10 mils of copper.

Other standards may nominate a specific resistance for

the installation. If space is limited, the contractor may be

required to install electrodes to a depth that achieves the

required value.

Chemical ground rods can be ordered as individual

components or as a complete kit. Kits include the chemical

electrode (pre-filled with electrolytic salts), Bentonite,

GEM backfill, and an access well. To order the chemical

electrode only, add “B” to the end of the part number.

Chemical ground electrodes, part of the ERITECH® line of

Facility Electrical Protection products from ERICO, provide

a low impedance ground in locations of high soil resistivity

and dry soil conditions. Used in conjunction with a bentonite

backfill and ERICO’s unique GEM material, the ERITECH brand

of chemical ground electrode system provides a method to

improve soil resistivity directly surrounding the electrode, and

can replace multiple conventional ground rods. It maintains

a low ground resistance, maintenance-free installation that

dissipates lightning energy and other dangerous electrical

fault currents, even in sandy or rocky soil conditions. The

chemical ground electrode is useful for providing an effective

earth in poor soil conditions where space for electrodes is

limited. Market applications include telecommunications,

power generation and distribution, commercial and industrial,

manufacturing, transporation (rail and aviation), lightning

protection, recreational facilities, and defense.

ERITECH brand of chemical ground electrodes are most

effective when installed as part of a total system that includes

high conductivity backfill materials, access/inspection wells,

and permanent, reliable CADWELD® connections. They may

be installed either vertically or horizontally.

Ground Enhancement Material

(GEM)

Developed in 1992, Ground Enhancement Material

(GEM) is a superior conductive material that solves your

toughest grounding problems. It is the ideal material to

use in areas of poor conductivity, such as rocky ground,

mountain tops and sandy soil. GEM is also the answer in

situations where ground rods can’t be driven or where

limited land area makes adequate grounding difﬁcult

with conventional methods. Only rarely do grounding

system designers and contractors get to work on a site with

good grounding conditions. Even under ideal circumstances,

soil structure can vary and make it difficult to achieve

uniform, low levels of resistivity across a wide area. Under

almost all soil conditions, the use of a ground enhancement

material will improve grounding effectiveness. Some are

permanent and require no maintenance. When selecting a

ground enhancement material be sure it is compatible with

the ground rod, conductor and connection material.

GROUNDING SYSTEM COMPONENTS GROUND ENHANCEMENT MATERIAL

Ground Enhancement Material

To improve the conductivity of a grounding system,

ERICO recommends using Ground Enhancement Material

(GEM).

GEM is a low-resistance, non-corrosive, carbon dust based

material that helps improve grounding effectiveness,

especially in areas of poor conductivity. GEM contains

cement, which hardens when set to provide a permanent,

maintenance-free, low-resistant grounding system that

never leaches or washes away. GEM does not adversely

affect soil and will not leach ions or contaminate ground

water. It meets all EPA requirements for landﬁll (USA).

A Material Safety Data Sheet (MSDS) is available on

request.

1. Premix GEM into a slurry form. Use 1.5 to 2 gallons

(5.7 to 7.6 liters) of clean-potable water per bag or

bucket of GEM. To mix GEM into a slurry form, use

a standard cement mixer or mix in a mixing box,

wheelbarrow, etc. Use 1.5 to 2 gallons (5.7 to 7.6

liters) of clean-potable water per bag of GEM. Do not

mix GEM with salt water.

2. Spread out enough GEM to uniformly cover bottom of

trench–about 1 inch (2.5 cm) deep. (See Table)

3. Place conductor on top of GEM. (See Note 1)

4. Spread more GEM on top of conductor to completely

cover conductor – about 1 inch (2.5 cm) deep. Allow

GEM to harden. Wait 30 minutes to one hour before

ﬁlling the trench with soil backﬁll.

5. Carefully cover the GEM with soil to a depth of about

4 inches (10 cm), making sure not to expose the

conductor.

6. Tamp down the soil, then ﬁll in the trench.

Note 1: Wait for the GEM to harden, about 15 to 20 minutes,

before placing the conductor on top of the GEM. You

must apply 4 inches (10 cm) of insulating material to

the conductors and ground rods exiting the GEM,

starting 2 inches (5 cm) inside the GEM.

Note 2: Excess standing water must be removed from trench.

Proper bonding is essential to create an equipotential

plane between service grounds and equipment during

fault and transient conditions. This equipotential

plane provides a near zero voltage differential and

serves to protect people and equipment during these

events. The most popular bonding product in use

today is the ground bar or bonding bar. Ground bars

provide a convenient, single-point grounding and

bonding location. Conductors are welded to the bar

using a CADWELD

exothermic connection or are

mechanically fastened by using lugs.

ERICO can design and manufacture custom bars. In

addition, the breadth of the product offering includes

TMGB bars, which meet the requirements of TIA

EIA

607 and conform to BICSI

recommendations.

Our perimeter bus system allows for fast and

easy field installation of halo and other perimeter

grounding schemes.

•2-footspacingbetweenconductors

•Terminationsthatprovideaconstantimpedanceover

•MultiplepathswithintheSRGtoallowthenoise

•Ameshmadeofflatcopperstripstoprovidethemost

functional low impedance and cost effective computer

grounding system available

•Weldedconnectionstoassureanoise-freebond

Welded Connections

Welded connections are often specified because they

are the only connections proven to assure a “noise-

free” bond. Normal shock and vibration jar mechanical

connections, creating electronic noise. This causes

relatively high Ldi/dt voltages, due to a sudden change

in connection impedance. This sudden change can

result in pulses which can be coupled onto the signal

circuits. These unwanted signals can create false data

or even cause permanent circuit damage. Corrosion,

dirt and cleaning fluids cannot interfere with the

molecular bond of a welded joint.

The importance of SRGs for

Computer Applications

In order to minimize the effects of noise,

many computer manufacturers, users

and government agencies have detailed

specifications regarding computer

grounding. Computer installations are

particularly sensitive to:

•Couplingbetweenadjacentpower,data

circuits and ground, where noise can be

introduced into cables — even nearby

lightning strikes can be a real threat.

•Noiselevelsfromnearbytransmitters

may be a serious problem and require

shielding.

Signal Reference Grid (SRG)

EQUIPOTENTIAL BONDING SIGNAL REFERENCE GRID (SRG)

The Signal Reference Grid (SRG) is a pre-fabricated, low

impedance network of conductors established to create

an equipotential plane for high frequency, low voltage

digital signals in such applications as intensive computer,

telemetry and telecommunications installations.

Digital signal line voltages are typically low. Their

sensitivity to transient noise is very high (typically 1 volt

for some digital systems). The SRG complies with IEEE®

Standard 1100-1992 for grounding practices in sensitive

electronic environments.

Proper grounding and bonding of sensitive electronic

systems, including computer installations, requires careful

consideration of all frequencies from DC to over 100

megahertz. The local requirements for electrical fault

current and lightning protection must also be met.

The safety grounding system required by code does not

address the special requirements of noise immunity. An

additional “grounding” system called the Signal Reference

Grid (SRG) is needed for trouble-free equipment

performance.

•Localcodesmustbefollowed.

•AllequipmentshallbebondedtotheERITECH® brand

of SRG using low impedance risers. Never connect to

strip closest to outside wall.

•Allraisedfloorswithinthecomputerroomshouldbe

bolted stringer type.

•Everysixthraisedfloorpedestalineachdirectionshallbe

connected to the SRG using a #6 AWG concentric copper

conductor. The connection to both thepedestal and the

SRG shall be a CADWELD exothermic connection.

•Allcolumns,conduits,waterpipes,ducts,etc.entering

the computer room shall be bonded to the SRG (at each

end of the room if these are horizontal).

•Powerdistributionpanelsandpowerdistributioncenter

should be mounted directly to the building steel or

bonded to it by a short length of grounding conductor

equal to the “green wire ground” but at least #4

AWG copper. The grounding wire inside any panel or

enclosure supplying AC power to the computer must be

bonded to its enclosure.

Equipotential Mesh and Mats

Prefabricated Wire Mesh

ERITECH® brand of prefabricated wire mesh from ERICO

is a convenient, efficient and economical means of

improving grounding systems at facilities with high-

voltage installations and wherever large area grounds are

required. Equipotential mesh reduces step potentials at

power plants and substations, and effectively minimizes

ground plane fluctuations at communications antenna

sites. Wire mesh is also an excellent ground screen,

reflector and electronic shield for large facilities.

Personnel safety mats, made of prefabricated wire mesh,

are ideal for systems designed to protect operators

against “touch potentials” at manually operated

disconnect switches.

Arc Weldable Bonds

Arc weldable bonds are 4-ft pieces of concentric

cable (19-strand) which are flash-welded to steel rod

for a bonding connection to structural steel and to rebar. Arc

weldable bonds are an economical alternative to exothermic

welding when only a few connections need to be made and an

arc welder is available on site. The rod is sized to match the

ampacity of the cable for fault currents. Complete instructions

are provided.

All cable is 19 strand concentric.
