Advanced manufacturing technology

Megger believes that the best way to secure good quality products and intellectual property is through excellence in

engineering and its production facilities.

Key processes and expertise are kept in-house, and engineering teams are located on-site at all the company’s

factories.

Advanced manufacturing technology including automated wave-solder machinery and robotic surface mount

component technology help keep costs down and quality up.

Taking the lead for safety!

As an essential aid to safer testing, Megger has

introduced a new and comprehensive family of test

leads for use with its insulation resistance testers.

Three metres long, and made from ultra-flexible

silicone-insulated cable to ensure long life, the new

leads cover virtually all requirements related to

insulation resistance testing at up to 10 kV.

For use in applications where the space for making

test connections is not restricted, the test leads are

fitted with large insulated clips. They have a

maximum jaw capacity of 34 mm, and an insulation

rating of 10 kV.

For applications where space is more restricted, but a

useful level of protection from the output of the

insulation tester is nevertheless required, the range

includes leads that incorporate medium-sized

insulated clips. With an insulation rating of 6 kV,

these leads have a maximum capacity of 18 mm.

In some instances, such as motor terminal boxes,

space for connecting the test leads is so restricted

that insulated clips cannot be used. For these

applications, Megger offers test leads with

uninsulated clips that have a maximum capacity

of 18 mm.

Leads with large, medium and uninsulated clips are

supplied in colour-coded sets of three – positive,

negative and guard.

Also included in Megger’s new test lead family are

leads designed to allow insulation resistance testing

to be carried out more safely on low voltage control

circuits in the vicinity of high voltage equipment.

With insulation rated at 1 kV, these leads are supplied

in sets of two, and incorporate probe-type tips with

push-on crocodile-clip adaptors.

A choice of 5 kV or 10 kV

insulation resistance

testers to suit needs and

budgets.

Why CATIV?

A small fault becomes a big problem on

Category IV high energy unfused supplies!

A distant lightning strike can produce a transient

of several kV on the supply. The transient may

only lasts for a few tens of microseconds and is

likely to do little damage.

The problem is that it may initiate an arc and

this arc then presents a low impedance path for

current from the mains supply.

Often, that supply can deliver 1000 A or more

until the breaker or other protective device

operates. In that time, the amount of energy

liberated is easily enough to start a fire or even

cause an explosion. If the arc is within a test

instrument there is a high probability that you

will be injured or worse!

The solution is simple – design the instruments

with protection and internal clearances that are

large enough to prevent transients from

establishing an arc and along with appropriate

protection devices. Guidance to this is given in

IEC61010 in order to comply with category

ratings defined in IEC60664.

In practice, transients are damped quite quickly

as they pass through a typical distribution

system. As you can see from the diagram CATIV is

recommended for use outside and to the

consumer unit. Specify Megger CATIV testers to

make sure you are safe and secure. Not only

could they save your life, but they are

economical too.

Using an instrument with a higher installation

category rating does not alone create a safer

working environment. You should always follow

correct work practices to keep you and others safe.

MetReport

Power quality analysis software

MetReport is an extremely

powerful, fully functional,

and stand-alone report

generation tool for the

Megger PA-9Plus power

quality analysers. Its primary

purpose is to dramatically

improve and extend

reporting capabilities.

In today’s economy, time is

money. Power and power quality professionals sometimes

spend countless hours every year creating customized reports

supporting their analysis studies. MetReport automates this

tedious task while improving the accuracy and reliability of

the entire reporting process.

MetReport utilizes data files obtained from the PA-9 and

PA-9Plus to rapidly produce completely customizable reports

targeted to your particular applications and requirements.

Some examples include: Power quality studies, harmonics

analysis, power factor and energy consultation, tolerance

curve studies (CBEMA/ITIC, SEMI F47, User Defined), auto data

analysis pass/fail reports, EN50160 compliance, and IEEE/IEC

Flicker. The key to quickly learning and using MetReport is

the integrated wizard function. This wizard effortlessly takes

you through the entire report creation, customization, and

generation process. Several sample report templates are

included for review, and may be modified to meet your

specific needs.

All reports are output as standard Microsoft Word

documents.

What makes MPRT a World Class test

instrument?

There are three distinctive components of the Megger MPRT

Relay Test System that set it apart from any other. These are:

• The Power Box

• A hand-held controller we call the TVI

(TouchView Interface)

• AVTS Basic Software (Advanced Visual Test Software)

The Power Box

It’s lightweight (yet extremely rugged), with unmatched

versatility.

Constant Power Output is sustained through the entire

“power curve” of a test. With a CPO of 200 VA current and

150 VA voltage, the MPRT will test any protective relay.

A unique modular VI-Gen Design combines the voltage and

current generator (VI-Gen) components into one amplifier

package.

By using multiple VI-Gens, the system can deliver up to four

voltages and four currents or with convertible voltage

channels eight currents.

The modular configuration also allows you to order the

system to fit your precise testing requirements and budget,

with an easy, flexible upgrade path.

Performance Proven

MPRT is recognized for its versatility, its impressive

power capability and an extra rugged design. Its

testing performance is proven every day in some of

the most remote areas of the world.

Plus, it keeps getting better with the addition of significant new

features and capabilities. These include:

Click-on-Fault – gives you the ability to define the type of

operating characteristic, then “click on” the characteristic to

test the relay.

Binary Search – used with Click-on-Fault, you can easily define

maximum values and type of fault or characteristics such as

constant current, constant voltage or source impedance.

RIO File Import – allows you to import an existing RIO file into

the click-on-fault diagram and then proceed with the test.

Dynamic Control – provides easy set up of multi-state dynamic

tests that are normally associated with trip and reclosing

schemes. In addition it gives you a simple means to create

complex waveforms for special test applications, using a new

feature called Wave Index. Wave Index can change the

waveform “on-the-fly” by incrementing individual harmonic

values in real time.

Recorder Capability – Used with Dynamic Control, capture all

analogue output waveforms, binary inputs and outputs, and

more.

Modbus Communications – automates communication with

various relays via Modbus protocol.

SSI File Reader – quick, easy import of state-sequence files

CABLE FAULT LOCATION 1716 CABLE FAULT LOCATION

Cable fault locationCable fault location

The fundamental objective of any cable fault location system is to provide quick, effective,

accurate and safe fault location, resulting in reduced system outages and “Customer

Minutes Lost”. Megger’s new PFL systems achieves all this, and more. The standard

system comes as a mobile, compact system to meet your local requirements. All systems

offer the facility to undertake cable testing.

lid.

All important tools of cable fault locating are consolidated

into one package: dc/tester burner, surge generator, and

radar coupling. When utilized with the MTDR Cable Analysis

System, the combined instruments provide the following fault

location techniques:

Time Domain Reflectometry

Digital Arc Reflection

Surge Pulse

PFL Series Cable Fault

Locators

The standard system comes as a mobile, compact unit to meet

your local requirements. All systems offer the facility to

undertake cable testing.

■Cable and fault diagnosis

■Prelocation of cable faults

■Fault conditioning

■Pinpointing locating using acoustic methods

Models PFL40-

1500 and 2000

Features include:

DC testing to 40 kV

Each instrument uses DC

testing to prove the integrity

and confirm fault conditions in

cable networks with a test

voltage up to 40 kV and a

current of 25 mA.

The variable output voltage

can also be used to test

sheaths requiring 5 or 10 kV

test voltages.

The operator selectable over-current trip levels provide

protection to the system under test in the event of the cable

under test breaking down.

Fault pre-location

Each system provides a variety of methods you can use to pre-

locate the fault position.

TDR mode – use a real time trace and a stored trace for

viewing simultaneously on the colour display, allowing

comparison and difference measurements to be determined.

Further, the TDR features auto-ranging, auto distance to fault

and operator assist functions that guide the operator through

the fault locating process.

A.R.M. (Arc Reflection Method) mode – the system stabilizes a

fault by creating a temporary “bridge” to earth. During this

condition a standard pulse echo measurement is taken into

what is basically a short circuit fault.

ICE (Impulse Current) and Voltage Decay methods – these are

also available and are transient analysis methods or pre-

location which utilize either a linear coupler or voltage

divider.

Fault conditioning

Also use the system to stabilize flashing, unstable or high

resistance faults, by employing A.R.M. and Proof/Burn

technology.

Proof/Burn

Following a breakdown of the cable under test, you can

employ the 40 kV dc output to apply a high current,

thus stabilizing the fault condition. This allows easier

and quicker pre-location and pinpointing of the unstable

faults.

PFL20M is easily manoeuvred

because of its compact design

and large wheels

A.R.M.

Although not widely thought of as a fault condition method,

the A.R.M. mode can be used in pinpointing faults.

Acoustic pinpoint fault location

Accurate acoustic pinpoint location of faults is achieved with

the powerful 8/16/34 kV (4 kV is optional) surge generator

(thumper), which comes in either 1500 Joules or 2000 Joules

configurations.

Additional accuracy can be achieved by using the Megger

MPP1001 or 1002 acoustic and electromagnetic pinpointer

which easily and accurately shows the direction and distance

to a fault.

PFL40 features a large, colour screen and intuitive software

which assists you in accurately tracing and locating cable

faults.

18 TIME DOMAIN REFLECTOMETERS

Time domain reflectometers

Time domain reflectometry – or TDR for short – is based on the simple notion of

reflecting an electrical signal from the fault back to your instrument, and measuring the

time. Megger has taken the concept, and added easy to use diagnostic tools that help

even inexperienced staff make expert assessments.

TDR1000/2P

Single channel cable fault locator

A state of the art TDR capable of identifying and locating

faults on metallic cables. The TDR1000 is suitable for use on

both dead or live cables without a blocking filter, up to CATIII

300 V phase-to-earth.

TDR2000/2P

Dual channel cable

fault locator

A state of the art mono or

colour display two-channel

TDR. capable of identifying

and locating faults on

metallic cables. The

TDR2000P is suitable for use

on dead or live cables

without a blocking filter, up

to CATIII 300 V phase-to-

earth with a range of up to

20 km. The TDR has an

internal memory and the

TraceMaster software

supplied allows storage and

analysis of waveforms on

a PC.

It takes less time to train users on

TDR1000/P, as each key has a

dedicated function, such as cursor

left and right, velocity factor,

range etc.

TDR2000/2P can identify and locate

a wide range of faults on metallic

cables from a few metres to 20 km

depending on cable type

How TDRs work

A TDR measures the time it takes a pulse to travel

down a cable, encounter an impedance change, and

reflect back. By knowing the velocity of the pulse the

TDR converts this time to distance. You can then

pin-point the exact location of the problem. Using a

Time Domain Reflectometer (TDR) such as

TDR1000/2 you can find the distance from the tester

to the end of the wire (up to 3,000 metres), along

with the distance to each anomaly within the circuit.

The problem could be in a terminal block, a wire

bundle, or a poor connection.

Problems with the dead zone

The width of the transmitted pulse affects the TDR’s

ability to identify reflections. The width of the pulse is

sometimes referred to as the dead zone. As the pulse

increases in width, it becomes more difficult to

identify reflections, because the dead zone may mask

closely spaced reflections. The TDR measures the

time it takes a pulse to travel down a cable,

encounter an impedance change, and reflect back. By

knowing the velocity of the pulse the TDR converts

this time to distance.

Velocity of Propagation

Pulses travel at different velocities on different cables.

The type of insulation and cross sectional area of a

cable will affect the velocity of a pulse. The velocity of

a cable can easily be determined by connecting onto

a sample of known length. Place the TDR’s cursor at

the reflection representing the end of the cable.

Adjust the velocity setting until the unit reports the

correct length. This setting will be the velocity of

propagation for the cable.

When the problem has been identified, it can be

corrected easily, certainly faster, and more efficiently

than rewiring the system.

MTDR1

Single-phase time domain reflectometer

Primarily used for the pre-location of cable faults using arc

reflection, differential arc reflection and impulse current

methods, the MTDR1 offers exceptional flexibility yet is

intuitive to use with facilities such as operator assist, auto-

ranging and auto distance to fault.

With a full built-in

keyboard and

Windows®XP

operating software

the MTDR has a

range of up to 30 km.

CABLE TRACE AND VOLTAGE DETECTORS 19

TTR300 series three-phase transformer turns ratio

test sets are designed to measure the turns ratio of

power, instrument, and distribution transformers in

a substation or manufacturing environment. A

rugged design makes the instruments well suited for

use in a variety of harsh environments. TTR300

series testers are ideal for use by power transformer

manufacturers. Their unique testing procedures and

storage capability allows you to set up and test

difficult three phase transformers (with multiple tap

changers and bushing CTs) in a fraction of the time

than it used to take. Tests include a pass/fail limit of

individual ratios and measuring the phase deviation

of the transformer primary versus secondary. This

quickly indicates problems in the transformer such

as partial shorted turns and core faults. This

measurement is useful in verifying phase errors in all

types of PTs and CTs. Each unit comes equipped

with a remote-control switch for single person

testing. This allows the operator to test transformers

with LTCs very quickly.

TRANSFORMER TESTING 2120 TRANSFORMER TESTING

Transformer testing

It’s tough work testing transformers when it’s cold and wet. Or even if it’s hot and the

sun’s baking on your back. Don’t worry, Megger’s new hand-held transformer test

equipment is tough and lightweight, with all the functionality you need for rapid testing.

PowerDB OnBoard - consistent and

repeatable

PowerDB OnBoard comprises the powerful PowerDB

asset management software embedded within the

instrument, running on a Windows operating system.

Without the need for an external computer, PowerDB

OnBoard brings field based users consistent,

repeatable tests across instruments, unprecedented

data analysis (including historical trend charting) and

asset management tools, all from on-screen ‘forms

based’ views.

Also included are a number of new communication

technologies, providing a near seamless interface

between the instrument and optional peripheral

equipment, such as an “in-lid” USB full-sheet (A4 or

letter) thermal-paper printer, USB flash drive, and

external PC (via Ethernet port). For advanced users, a

USB router can be connected to the instrument to

provide simultaneous access to other equipment,

such as a mouse or a keyboard. Storage space is

provided by either the internal flash memory or

external USB flash drive - sufficient to save literally

tens of thousands of test data sets.

Reduced training time

A common user interface reduces the training time

needed to understand the different instruments that a

busy test engineer has to use. New instruments with

PowerDB OnBoard such as TTR330 are truly forms-

based, have a large 8.4” full-VGA bright colour display,

and let you set up and control the instruments

through on-screen test form views. On-screen test

forms are exact replicas of the test forms which are

printed as a permanent test form record once testing

is complete. They are secure reports and generated

directly from instrument so no human interface is

needed.

Transformer winding resistance and

tap-change test set

Field portable low resistance measuring instrument designed

to test transformer windings, motors, generators and tap

changers. The two independent measuring channels greatly

reduce the test duration of large inductive loads like

transmission transformers, where it is possible to measure

secondary and primary windings simultaneously.

A lightweight, field portable unit that safely and accurately measures the

DC winding resistance of all types of transformers and rotating machines

MCTT-10

Current transformer tester

MCTT10 is a portable unit for performing saturation and ratio

tests on current transformers using the voltage-comparison

method. It provides a variable voltage output and precision

instrument for testing single and multi-ratio CTs. Saturation

and ratio tests can be performed without changing any leads.

Current transformers can be tested in their equipment

configuration, such as being mounted in transformers, oil

circuit breakers or switchgear. However it is necessary for the

equipment to be totally isolated from the electrical system

prior to testing.

MCTT-10 performs saturation and ratio tests on CTs using the voltage-

comparison method

MCT1600 has a manual

voltage output control

knob. The user can perform

any test required manually if

only a spot check is needed.

MTO210

Transformer ohmmeter

MTO210 is a line-operated, field-portable instrument

designed specifically to measure the d.c. resistance of all types

of magnetic windings safely and accurately. It is mainly used

all types of transformer windings but can also test rotating

machine windings and perform low-current resistance

measurements on connections, contacts and control circuits.

Three features combine to make this instrument unique

■dual measurement

■load tap-changer testing

■safety shutdown

The dual set of potential inputs measure the resistance of the

primary and secondary windings of a single- or three-phase

transformer simultaneously speeding up the measurement.

To achieve a tenfold improvement in reading time, a

balancing current is applied to the secondary to attenuate

the circulating current induced when the test current is

applied to the primary winding.

When testing the windings and contact resistance on tap-

changers with make-before-break contacts and voltage

regulators, the internal shutdown circuit of MTO210, which

will be triggered by a voltage kickback of a few microseconds

if the tap-changer contacts are opened, can be used to check

for pitted or misaligned contacts as the instrument will shut

down if either condition occurs.

Users are protected by the shutdown circuit safety feature:

any inadvertent disconnection of a test lead or loss of power

to the instrument will safely discharge the energy stored in

the test sample.

MTO320

Transformer ohmmeter with graphical

interface

MTO320 provides a fully automatic six-winding resistance

measurement capability, even on 3-phase transformers with

tap changers. During tap changes, the unit also continuously

monitors for any break-before-make conditions.

The high contrast bright 5.7” full VGA colour display can be

clearly read in direct sunlight. The graphical user interface

allows automated setup and control through easy-to-read

icon based screens. The full QWERTY keyboard speeds the

entering of information such as nameplate-type data.

Communications is via RS-232, USB and Ethernet ports for

easy on-board printing and storage, and downloading of test

results.

Once testing is complete, the unit will automatically

demagnetize the transformer.

Supplied with PowerDB LITE PC software application, the

user can perform data analysis and trending of results.

MTO measures dc resistance of all

types of transformer windings

within the defined ranges of

current and resistance.

Transformer testing

Karl Fischer testing uses the titration method to measure the amount of water in fluids

such as insulating oil. It has become a standard test done on transformer insulating oil.

Oil is an efficient coolant with a high flash point and high dielectric strength when used

as an insulator in transformers. The insulation properties can change due to oxidation,

acids, sludge, gas and water absorption. These changes can be monitored using a

dielectric Megger OTS test set.

Calibration meter

A useful device for verifying the calibration of the AF series

of oil test sets.

Insulating oil Karl Fischer

Polarity

Moisture in insulating oil not only reduces the

efficiency of the oil as an insulator but may also be

used to detect signs of degradation in the solid

insulation in transformers and switchgear since water

is a by-product of the breakdown of this type

insulation. However oil degrades in the light and

over time, and water content should be measured at

or near the normal operating temperature of the oil.

KF875

Portable moisture in insulating oil test set

Easy to use, portable one button test set with integral

printer. Can be powered from mains, internal rechargeable

battery or car battery. Ideal for on site use.

It is now recognised that inaccuracies can occur when

oil is sent to a central laboratory or workshop for

breakdown and water content analysis. Local testing

allows decisions to be made immediately reducing the

danger of putting the equipment back into service with

inadequate oil whilst waiting for results to come

through from a central laboratory.

guide to low resistance

testing. This 32 page

written in a clear, easy

to read style. The

booklet

comprehensively covers

both theory and

practise. It has chapters

on how to measure low

resistance, choosing a

low resistance tester,

and evaluation and

interpretation of results

Why test for resistance?

Low resistance measurements are required to prevent

long term damage to existing equipment and to

minimize energy wasted as heat. They indicate any

restrictions in current flow that might prevent a

machine from generating its full power or allow

insufficient current to flow to activate protective

devices in the case of a fault. Periodic tests are made

to evaluate an initial condition or to identify

unexpected changes in the measured values, and the

trending of this data helps indicate and may forecast

possible failure conditions. Excessive changes in

measured values point to the need for corrective

action to prevent a major failure.

BATTERY TESTING 2928 BATTERY TESTING

Battery testing

With the increasing dependency of back up systems on battery strings, and the escalating

cost of replacing failing cells; instrumentation and software systems that can measure

trend and manage the life-cycle of cells is a cost effective option.

Are batteries a waste of time and

money?

Batteries are indeed, a waste of money. This means to

say that if the power grid were 100% reliable,

batteries would not be necessary!

The many worldwide power outages over the past

several years make batteries essential as a backup

source. Who actually gives batteries a second

thought? We simply expect them to work when called

upon. Experience has shown that this expectation is

pure fiction.

Batteries are extremely important to provide

electricity to support many assets and revenue

streams during outages. For example, in a generating

station, if the turbine suffers an outage, without the

back-up battery the turbine lube oil priming pumps

would not continuously keep the bearings lubricated

causing major damage and lengthy outages. In

hospitals, who wants to be in the middle of an

operation when an a.c. outage occurs without proper

battery back-up? The applications for batteries are

innumerable and frequently unseen. In this world of

dependency upon electricity, it is impossible to

survive without battery back-up.

It is not enough to only check the voltage and

specific gravity. The sum of all of the cells’ voltages

equals the charger output. Voltage (and specific

gravity) of lead-acid batteries follows the sulphate. If a

battery is fully charged, the sulphate will be in the

acid and its voltage and specific gravity will be normal

(with few exceptions.) If it is in a discharged state,

the voltage will be low and as there will still be some

sulphate on the plates, the specific gravity will also be

low. If the battery has a normal voltage, there is no

indication of its condition. When the voltage is

abnormal, it may indicate a potential problem.

There are many failure modes for batteries. With care

and measurement these can be dramatically reduced,

especially if little to no testing is presently being

performed. The battery is installed, not to add to

work load, but to support critical electrical

equipment or revenue streams. Proper testing and

data analysis can help determine when a battery

should be replaced. Testing also helps reduce

emergency battery replacements and assists in

budgetary planning, thus reducing cost. A properly

implemented battery testing regime does not

necessarily reduce the work load but it will, most

likely, increase reliability of the entire d.c. network.

You have a right to safety

EN61010 - 1:2001 is very specific about transient

immunity. In the section on "Circuits or components

used as transient overvoltage limited devices", the

standard specifies the performance of components

and their applicable impulse withstand voltage.

Megger recommends that wherever possible, you

should specify CAT IV instruments that keep you and

your electrical instrumentation safe. In most cases,

Megger has doubled the impulse withstand voltage

from 4kV to 8kV. In addition nominal mains supply

has increased from 300V to 600V for your protection.

TEST AND MEASUREMENT SOFTWARE 3736 TEST AND MEASUREMENT SOFTWARE

Simplifying the Compilation and Reporting

Process

The new PowerDB software package eliminates many

common paperwork and recording problems. With the

software, the number of man-hours devoted to preparing

reports will be minimal. The user can customize the reports

to be what a job requires but will not have to write the

report, which is automatically generated by the software.

Included in the reports are a table of contents, data sheets,

as well as comment and deficiency summaries. PowerDB

even comes with a built-in spell check.

Automatically generated professional reports means that a

testing company, for instance, is able to complete jobs

faster and in a more efficient manner. PowerDB is

well-suited for technicians who prefer to spend a

minimum amount of time writing reports and want a more

concise way to process data.

Electronic records of test data can create a couple of

different problems for companies and utilities. While many

electronic records are hard to locate due to the vast

amount of records kept on one system PowerDB makes it

easier. By using its relational database it is much easier to

find present and past records. And, because it has multiple

safe guards, PowerDB prevents lost data. By saving

documents that are in progress to multiple places, the

problem of lost data is eliminated. PowerDB also

synchronizes the date to several machines, meaning that a

single crash does not create a costly loss of data.

Test and measurement softwareTest and measurement software

PowerDB

Acceptance and Maintenance test data

management software

A powerful software package that offers a revolutionary

approach to managing electric utility and industrial electrical

testing data. The software is designed from a ground-up

approach, and is easily the most advanced package on the

market. It employs over 160 industry standard test forms that

have been developed and used by industry specialists during

the last 20 years.

The software package provides data management for electric

utility companies, electrical testing services acceptance jobs,

or maintenance testing jobs. Data entry, storage and creating

reports are all features of the software. In a single step,

PowerDB is able to quickly create entire test documentation

packages that include test reports, comment and deficiency

summaries, table of contents and field service reports.

In addition, users are able to use this flexible software to

define data forms and customize them to different

device types.

PowerDB’s test forms are designed to be used with each

of the following Centres:

Batteries Insulation Fluids

Cables Loadbreak Switches

Circuit Breakers Motor Control

Coordination Data Power Factor Tests

Disconnects Relays

Generators Switchboards

Ground Fault Tests Transfer Switches

Ground Mat/Grid Tests Watthour Meters

Instrument Transformers Transducers

directly into data

fields. Second,

forms can be filled

in using other

applications,

including Megger’s

Advanced Visual

Test Software,

entering data into

the fields using

information stored

in the other applications. Finally, data fields can be filled in

using manual entry. This allows the user to enter the exact

information that is desired.

Built-in Report Flexibility

PowerDB can create reports in one step, with customizable

sorting of the order of test forms. Forms can be removed, and

page numbering will be automatically adjusted. In a single

print job, supplemental reports can also be printed at the

same time as the primary report. The supplemental reports,

including comment and deficiency summary reports, open up

the data and information for all of the equipment tested on

one job. Finally, all of the information can be generated for

the on-demand world using the optional PowerDB Web

server. All of the user’s important information is published to

the Web and can be accessed from anywhere in the world.

Computerized Maintenance Management System Support

Many electrical utilities and other company operations have

invested in sophisticated CMMS systems, such as Digital

Inspection’s Cascade and MRO Software’s MAXIMO. However,

due to test instrument specific software packages and hand-

written test results, these firms often struggle to get test data

into their systems. One electric utility even referred to getting

data into the CMMS as ‘feeding the monster’. PowerDB’s

speciality IS ‘feeding the monster’.

PowerDB allows you to link easily with the CMMS system so

that the system can pre-populate the PowerDB equipment

database, send PowerDB all work orders, add forms based

on the job plans, and even return the measurement

points, obtained from a multitude of test sets, back to the

CMMS system.

Furthermore, Megger will work directly with your CMMS

personnel to integrate your data into your internal CMMS

system.

Easier

Management of

Test Data

This easy-to-

operate software

offers a straight-

forward approach

to data

management. The

first basic step in

creating this user-

friendly package

was to make test

data entry screens

and printed forms identical. Users will appreciate that what

they see on the screen is what they will see in the printed

version. PowerDB also simplifies testing and data

management by allowing users to deliver reports

electronically using e-mail, CD-ROM, web server and PDF files.

The software will

also execute

several tasks for

the user,

including

equation

calculations,

temperature

correction factors

and charting.

PowerDB helps

predict possible

equipment

failure by

trending previous results, which can be stored using PowerDB

or imported from other software. This makes transitions from

other software to PowerDB easy, and users can be prepared

for possible problems with equipment.

The industry standard test form is not always what a company

needs, and because of that, the PowerDB software allows the

user to customize forms. With a drag and drop feature

anyone, even those without database experience, can create

a form simply by dragging and dropping in tables, text boxes,

images, charts and more, to create a customized form. And,

with VBScript, calculations can be defined,

tables looked up, and it can even interact

with other applications. One time definition

of common items can be used to put logos,

headers and footers on every page or in

many multiple forms. One change will

automatically update every form the

common item is used in.

There are three

ways to document

testing using the

PowerDB software.

First, the software can

communicate directly

with test and measurement

equipment produced by

Megger. This allows

these products to

enter the

results
