Current transformer (CT) testing

Why testing CTs?

Testing current transformers helps to detect installation

related and in-service related problems, such as:

Installation related

> Transportation damages

> Wiring errors

> Manufacturing defects

In-service related

> Degradation of accuracy class

> Shorted turns

> Magnetized core

> Burden failures in secondary circuit

> Insulation material failures

With the CPC 100 many standard electrical tests for CTs

can be performed with one single device saving testing

time and labor costs. Additionally, unconventional CTs, like

Rogowski coils and IEC61850 integrated systems, can also

be tested.

CT testing with the CPC 100

Supplied from a single phase wall outlet, the CPC 100

can generate up to 800 AAC (2 000 A with CP CB2 current

booster) for injecting into the CT‘s primary side and

testing its ratio, polarity and burden.

Excitation curve measurement

For excitation curve measurement, the CPC 100‘s output

is connected to the secondary terminals of the core. Within

an automatic test run, the CPC 100 measures the excitation

curve and displays the knee point voltage and knee point

current at rated frequency (according to the relevant IEC

or IEEE / ANSI standard). The CPC100 also automatically

demagnetizes the CT core after the test.

Your benefits

> Mulifunctional CT tests

> Primary injection up to 2 kA

> Simple wiring test with handheld

polarity checker (CPOL2)

> Voltage withstand test up to 2 kV

+ CPOL2

The CPOL2 can check the correct

polarity along the different

connection points in the secondary

wiring by analyzing the sawtooth

signal injected into the CT’s primary

side using the CPC 100.

> IEC 61850 Sampled Values testing

Winding resistance measurment

Using the winding resistance measurement function also

allows the user to calculate the accuracy limiting factor (ALF)

for protection circuits and the instrument security factor (FS)

for metering circuits.

Power/dissipation factor (PF/DF) measurement

When combined with the CP TD1, the CPC 100 is also

capable of performing PF/DF measurements. This helps

to assess the insulation condition of the CT.

+ CP CB2

With the CP CB2 primary injection of

current up to 2 kA can be realized for

CT testing.

+ CP TD1

For high-voltage CTs, insulation material

tests are very important and can be easily

done with the CP TD1 accessory.

Voltage transformer (VT) / potential transformer testing

VT testing with the CPC 100

With a voltage output of up to 2 000 VAC the CPC 100 can

be used to test VT ratio, polarity and burden.

By injecting voltage into the primary side, ratio can be mea-

sured. Thereby the phase angles of high-voltage output and

voltage measurement input are also measured. Thus the

correct VT polarity can be verified.

Applying voltage to the secondary VT circuits and measuring

the load current in amplitude and phase allows the actual

burden to be measured, ensuring that it is within the VT´s

specification data.

Why testing VTs?

The majority of VT failures occur due to electrical stresses

or manufacturing and installation errors. Typically electrical

stresses are caused by:

> Thunderstorms

> Ferro-resonances effects

> Over-voltages

Especially in high-voltage and extra high-voltage

installations supervision of the VT insulation system is

important to ensure that its dielectric characteristics have

not degraded over time.

In case of (re-)commissioning of substations VT circuits

should also be checked. Verifying the VT´s nameplate data

helps to identify damages of the VT or wrong connections.

Your benefits

> Ratio testing from 15 Hz - 400 Hz

> Multi-functional VT testing

> Simple wiring check with handheld

polarity checker (CPOL2)

Voltage transformer (VT) / potential transformer testing

+ CPOL2

The CPOL2 can check the correct polarity

along the different connection points in

the secondary wiring by analyzing the

sawtooth signal injected into the VT’s

primary side using the CPC 100.

Voltage/potential transformer testing

> IEC 61850 Sampled Values testing

> Power/dissipation factor test

up to 12 kV, 300 mA | with CP TD1

Disturbance-free measurement

The VT‘s secondary signal may be difficult to measure if it

is small in amplitude – especially if neighboring parts of the

substation are in operation. In case of strong disturbances,

the user can select a frequency different to that of the

power system and utilizes the “frequency selective mea-

surement” function. Thus only the VT‘s output signal with

this particular frequency is measured while all other signals

are filtered out.

+ CP TD1

For high-voltage VTs, insulation material

tests are very important and can be easily

done with the CP TD1 accessory.

Power transformer testing

Winding resistance measurement

The CPC 100 provides an easy and accurate (4-wire connection)

winding resistance measurement. Automatic measurement

for tapped windings (by using CP SB1 with the on load

tap changer) speeds up the measurement. The CPC100

automatically discharges the inductive energy, which makes

the measurement safe.

Demagnetisation

After switching off a transformer or after applying DCsignals

to a transformer, the core remains magnetized. This can cause

problems for further diagnostic measurements or can lead

to higher inrush currents. By using the CPSB1 switch box the

integrated algorithm in the CPC 100 completely demagnetizes

the transformer core.

Ratio & excitation current measurement

For measuring ratio and excitation current, the CPC 100

provides a 2 kV output, delivering 2500 VA. The test voltage

is generated digitally and the current is automatically

measured within the CPC 100. This makes the measurement

highly accurate, easy to set up, fast and safe.

Testing power transformers – Most common

electrical tests with one device

Testing to assess the health of power transformers and

to diagnose problems is of utmost importance to ensure

the long-term and safe operation of these very expensive

power assets.

With the CPC 100 power transformers and their ancillary

components can be tested:

> Windings

> Tap changer

> Bushings

> Insulation

> Core

> Connection leads

> Surge arrestors

Power/dissipation factor (PF/DF) measurement

For PF/DF measurement on power transformers and

bushings, the CPC 100 is combined with the CP TD1.

Measuring this factor over a broad frequency range – in

addition to mains frequency – helps to better assess the

insulation condition, for example detect whether the

cellulose or the oil is contaminated by moisture.

Dynamic resistance measurement (DRM)

The DRM can be performed as a supplementary

measurement in order to analyze the OLTC’s switching

process. The CPC 100 + CP SB1 injects a DC current in

the same way that it does for static winding resistance

measurements with the the addition of recording the

dynamic behaviour of the diverter switch. Based on this

non-invasive testing method, failures can be detected

without opening the OLTC compartment.

+ TRC1

The triple remote control

TRC1 allows three CPCs to be

synchronized safely. This allows

the CPC 100 to be used as a

powerful HV source. Matching

transformers are provided in

order to match the rated voltage

on the LV side.

+ CP SB1

The switchbox CP SB1

reduces wiring work at power

transformers. Thereby, the

time needed for testing

can be reduced and, at the

same time, safety can be

significantly increased.

+ CP TD1

Insulation condition assessment

of transformers, bushings and

insulation fluids (with the CP TC12).

HV-source

Line impedance measurement

Line parameters for distance protection

Correct line parameters are crucial for reliable and selective

distance protection. The set of parameters contains the

positive and the zero sequence impedance (Z1, Z0) as well

as the k-factor (kL, RE/RL and XE/XL, k0).

These parameters are often calculated from software

tools, which do not provide actual line parameters due to

unknown soil properties, such as different soil resistivities,

pipelines or other unknown conductors. This leads to

under- or overreach of your distance protection relay

resulting in outage and loss of grid stability.

Zone under- and overreach

The most frequent faults on power lines are ground faults.

In particular, inaccuracies from software calculation effect

this kind of fault. The example on the right shows a zone

overreach for a ground fault due to an incorrect k-factor

setting. In this case the assumed k-factor is higher than the

actual one. Therefore, a ground fault at the remote end of

the line is seen incorrectly in the first zone.

Mutual coupling

With this unique testing equipment, the mutual coupling

impedance between parallel lines can also be determined

to consider coupling effects for correct parameterization.

Testing with the CPC 100

The main unit CPC 100 generates the frequency variable

test current and measures current and voltage by applying

digital filtering for high accuracy. The complex loop

impedance is then calculated accordingly.

The CP CU1 provides galvanic isolation between the line

under test and the CPC 100 as well as impedance matching

for short and long lines.

The CP GB1 protects the test equipment and the user

from any unexpected overvoltage on the line under test.

Furthermore it allows a direct connection to the power line

for a convenient execution of the test.

A dedicated test template provides the positive and

the zero sequence impedance as well as the k-factor in

commonly used formats. Furthermore it shows the actual

zone reach for each fault type based on the measured

values and relay parameters that are currently being used.

+ CP CU1

The CP CU1 allows the safe connection

of the CPC 100 to a power line or

HV cable. The impedance matching

transformer within the CP CU1 ensures

optimum power transfer from the

CPC 100 to the power line.

Ground grid CP GB1

Grounding system testing

Personnel safety

In the event of a ground fault hazardous step and touch

voltage can occur inside and outside of a substation.

Ground tests prove the effectiveness of grounding systems

and guarantee safety of people inside and outside the

substation.

A fall-of-potential measurement is usually performed to

determine the condition of the entire ground grid. On top

of that, step and touch voltages are measured at exposed

locations in order to ensure human safety in select areas.

Fall-of-potential measurement (3-point test)

The fall-of-potential measurement with the CPC 100

is performed according to EN 50522 or IEEE 81.

For the fall-of-potential measurement the voltage

between the ground grid and ground electrodes in

different distances to the ground grid is measured

until reference ground is reached. Dedicated software

transforms the test results into a voltage and impedance

chart which allows the ground potential rise and the

ground impedance to be determined.

Your benefits

> Determine true test values by

voltage measurements with handheld

HGT1 device

> Reduction factor measurement on

Ground grid

Grounding system testing

When testing large ground grids the potential of the ground grid under test and

the counter electrode must not overlap. This is done in order to ensure human

safety in a worst case scenario, which is always crucial. The CPC 100 + CP CU1

overcomes this problem by injecting the test current into a remote substation via

an existing power line.

> Reduction factor / current split factor

> Measure multiple current paths with Rogowski coil

Step and touch voltage measurement

Step and touch voltage measurements according to

EN 50522 and IEEE 81 are performed with the HGT1.

This handheld device employs frequency selective

measurements for effective noise suppression.

Furthermore, tests can be executed quickly and easily since

long test cables for connecting to the main device are no

longer necessary.

Dedicated test templates assess measured step and touch

voltages according to EN 50522 and IEEE 80 automatically.

+ HGT1

Primary Test Manager (PTM) and

HGT1 enable you to quickly, simply

and conveniently measure ground

impedance as well as step and touch

voltage. Due to a new approach there

is no operational personal required at

the CPC 100 anymore. Together, the

test director and assistants perform all

measurements out in the field in order to

avoid miscommunication and selection of

inadequate test points.

Ground grid CP GB1

Rotating machines diagnosis

Why test rotating machines?

Rotating machines, such as motors and generators, are

highly important components in power generation and

industrial applications. Therefore machine reliability and

availability are in high demand. Motors and generators are

exposed to high thermal, mechanical and electrical stress

that influences their reliability and life expectancy.

Premature failure may lead to significant economical

losses, due to unexpected outages and possible damage to

the asset itself. In order to plan maintenance effectively, it

is essential to have accurate condition information about

when components need to be repaired or replaced.

A variety of electrical tests can be performed with the

CPC100 over the complete life cycle of machines to

increase their reliability, prevent premature failures and to

extend reliable service life.

Your benefits

> Portable HV source

> High accurate PF/DF measurement

maximum usability

> Defined voltage steps for a combined

partial discharge and PF/DF

measurement enable reproducible

test conditions

PF/DF measurement and PF/DF tip-up test

The PF/DF measurement is used as a maintenance tool for

entire windings. The portable solution CPC 100 + CPTD1 +

CPCR500 allows PF/DF measurements to be carried out at

nominal frequency.

The measurement results can be compared with previous

measurements, factory acceptance tests or a phase-to-

phase comparison can be made. An acceptable

PF/DF offers assurance that the insulation condition allows

reliable operation.

Furthermore, a parallel partial discharge measurement

allows for a more detailed diagnosis of the type of fault.

The CPC 100 + CP TD1 can be used as HV source for the

partial discharge measurement.

The measurement complies with international standards

such as IEC 60894 and IEEE 286.

+ CP TD1

Insulation condition assessment of

motors and generators. The CPC 100

+ CP TD1 can provide up to 12 kV. It

can be be used as HV source and

PF/DF measurement system at the

same time.

DC winding resistance measurement

A DC resistance measurement is performed to detect

possible contact problems in the stator and rotor winding

of a machine.

The CPC 100 offers an integrated micro ohmmeter with

a maximum output of 400 A. The 4-wire method is used

to detect connection problems in the stator winding (bad

soldering contacts) as well as contact problems on the pole

connectors of the rotor winding.

Both failures can be the root cause of a local hotspot and

potentially damage the machine.

Pole drop test

Mechanical stress in rotor windings cause inter turn faults

(short circuits), which can lead to a magnetic imbalance.

This causes higher shaft vibrations which puts more stress

on the bearings and can potentially damage them. The

CPC 100 provides the AC source and the accurate voltage

inputs nedded to perform the pole drop test.

Gas-insulated switchgear testing

Testing gas-insulated switchgear to date

Gas-insulated switchgears (GIS) are compact and are,

therefore, used in applications where space is limited. For

commissioning of GIS a high-voltage (HV) withstand test is

required in accordance with standards (IEC62271-203).

To date the test voltage needed for a withstand test has

been produced by a resonance circuit. This test system

consists of an HV test transformer, a coupling capacitor

and a power control unit. The HV test transformer and the

coupling capacitor have to be connected directly to the GIS.

Weak points of this testing principle:

> The complete test system is difficult to transport,

because it consists of very heavy and large

components.

> It is difficult to use it at test sites with limited space,

such as wind turbines.

> The HV test lead must be connected to, and

disconnected from, the GIS system for testing. This

normally includes a time-consuming venting and

refilling process of the SF6 gas.

Innovative GIS testing

With the CPC 100 + CP RC it is possible to perform GIS tests

without the need of a big HV transformer. This is possible

because the system directly makes use of a specially

designed “PowerVT” for testing.

This Power VT is an integral part of the GIS and generates

the required test voltage. CPC 100 injects power at the

LVside of the VT, producing the necessary voltage on the

HV side. A direct connection of the measuring system to

the integrated VT of the GIS system eliminates the need

for draining and refilling any SF6 gas.

The CPC 100 + CP RC system comprises several small and

light-weight components (< 21 kg / 46 lbs) which can

be transported by one person. With its modular design

GIS tests can even be accomplished at test sites with

limited space.

With the compensating reactor

4 mH CP CR4 or 6mH CPCR6

the CP CR compensates the

capacitance in a modular fashion.

+ CPAT1

The auto-transformer CP AT1

allows to connect the mains

supply of the CPC 100 to a

three-phase 16A power outlet,

and delivers the required power

for the test setup.

+ CP TR

The isolation transformer CP TR

provides a potential-free output

signal and compensates the

capacitive load.

Powerful voltage withstand testing

When combined with the CP RC1, the CPC 100 allows

withstand tests with a maximum test voltage of 200 kV

to be carried out on GIS systems up to a rated voltage of

123 kV. The CPC 100 + CP RC2 is appropriate for testing

GIS systems with a rated voltage of up to 145 kV and a

maximum test voltage of 235 kV. This package is supplied

with the additional CPAT1 auto-transformer to guarantee

the necessary output power of the CPC100 for higher loads.

HV source for partial discharge measurements

During production or maintenance, impurities can occur

in GIS. These can cause major problems in operation.

Therefore, it is recommended to perform a partial discharge

measurement during commissioning (acceptance tests).

While performing these measurements with our MPD series

the CPC 100 + CP RC can be used as the HV source.

Switchgear and circuit breaker testing

Contact resistance measurement

The CPC 100 can measure contact resistance by injecting a

current of up to 400 ADC into the contacts and measuring

the voltage drop (using the 4-wire method). The resistance

value can be compared to the value given by the manufac-

turer as well as to previous records.

Why test switchgear and circuit breaker?

Switchgear consists of busbars, circuit breakers (CB),

disconnectors and earthing switches. There are various

connections and contacts within the switchgear. Poorly

maintained or damaged contacts can cause arcing, single

phasing or even fire which can lead to the total loss of

the asset.

Therefore, it is common practice to conduct contact resis-

tance measurements to ensure that the connections have

been made with the appropriate contact pressure.

Additionally, the insulation of CBs within the switchgear

has to be tested. These assets are frequently exposed to

Insulation testing of circuit breakers

For power/dissipation factor measurements on CBs, the

CPC100 is combined with the CP TD1. Measuring this

factor over a wide frequency range – in addition to mains

frequency – helps to better assess the insulation condition.

Commissioning and trouble shooting of protection systems

CT & VT performance check

The CPC 100 allows the verification of the ratio and polar-

ity of CTs and VTs – preventing wrong connections, espe-

cially in the case of tapped CTs. Injecting current or voltage

into individual CTs / VTs and checking the reading at the

relay ensures that phases are not mixed up and that the

CT and VT ratio setting in the relay is correct.

The CPC 100 can also measure the burden on the CTs

and VTs and, by determining the CT’s excitation curve, it

ensures that the protection circuits are connected to the

appropriate CT cores.

Wiring check

The CPC 100 can help to verify that the secondary wiring

is correct. By injecting a sawtooth signal into the CT or VT,

the operator verifies with a handheld device that the signal

has the correct polarity at the connection points of the sec-

ondary systems.

Commissioning protection systems

In order to work properly, protection and control systems

have to be correctly integrated into the substation or

power plant. Quantities from the primary system are trans-

formed at the VTs and CTs – using their different cores

– and so the voltage and current signals must be correctly

connected to the protection relays, automation units and

meters.

From these protection and control units, the trip signals

are routed back to the primary apparatus, for example,

the circuit breakers. A fault in any part of this system may

result in a system failure – false tripping or a failure to trip.

To prevent such a failure, the system’s functionality can be

verified by injecting into the primary side of the CT or VT

and checking the measured values at the relay or automa-

tion unit. Finally, injecting current at the magnitude of

a fault should result in the tripping of the circuit breaker,

which allows the verification of the complete chain.

The CPC 100 can inject up to 800 A (2 000 A

with the CP CB2) or up to 2 kV as well as a

sawtooth polarity check signal into CTs or

VTs in the HV yard, hence performing testing

on the whole system.

Timing of CBs with overcurrent elements

For testing of CBs or load breaker switches with integrated

overcurrent elements, the CPC 100 can inject AC primary

currents up to 800 A (or 2000 A together with the current

booster CPCB2), and measure the time from the start of

the injection to the interruption of the current.

Primary injection

With the CPC 100 primary faults can be simulated to check

if overcurrent, differential or distance relays operate cor-

rectly. The total trip time including the CB operating time

can also be measured in this test.

+ CPOL2

The CPOL2 can check the correct polarity

along the different connection points

in the secondary wiring by analyzing the

sawtooth signal injected into the VT’s

and CT´s primary side using the CPC 100.

IEC 61850-9-2 Sampled Values testing

IEC 61850

The standard for “Communication Networks and Systems

for Power Utility Automation”, IEC 61850, utilizes network

technologies for all types of information exchange.

Within IEC 61850, protocols for the transmission of

instantaneous voltage and current values are specified.

The sensors used in the transmission process can be

conventional CTs and VTs as well as unconventional

current and voltage sensors.

Your benefits

> Ready for applications in digital

substations

> Closed loop testing of merging units

> Primary injection works independently

of the sensor technology used

Sampled Values

A merging unit (MU) collects the measured current and

voltage values from the current and voltage sensors. Then

it merges the digitized values, which are called “Sampled

Values” (SV), into a data stream published to the substation

network.

Using this method, measured values (for example, the

bus voltage for a busbar protection scheme) can easily be

distributed to multiple bay devices.

IEC 61850-9-2 Sampled Values testing

Sampled Values testing with the CPC 100

The CPC 100 test system performs closed-loop testing

whereby a test signal is injected on the primary side

of the current / voltage sensors. The MU converts the

sensor output into a SV stream which is published to the

substation network. The CPC 100 then reads the data

back from the network in order to perform a variety of

different tests.

Automatic MU and channel detection is achieved by

injecting a test signal with a specific wave form. An

optimized and time-effective algorithm searches for the

unique test pattern within all the available MUs on the

network to identify the correct channel for testing.

The CPC 100’s SV test card operates according to the

“Implementation Guideline for Digital Interface to

Instrumental Transformers using IEC 61850-9-2” published

by the UCA International User Group.

CPC 100

The CPC 100 injects a sinusoidal test

signal to perform tests such as the ratio

test. Additionally, the CPC 100 generates

specific periodic wave shapes to identify

the correct MU and corresponding test

channel.

Operation of CPC 100: front panel

Operating from the front panel

Selecting test cards directly

Operating the CPC 100 manually provides the quickest

results with minimal training and preparation – perfect for

users who only operate the device occasionally. The user just

selects the test card to be used, connects the CPC 100 to the

asset and performs the test by pressing the start button.

Using pre-defined test templates

Additionally, pre-defined test templates help the user to

perform frequently used tests conveniently and efficiently.

A number of test cards (for example, power/dissipation

factor, winding resistance, ratio measurement,etc.) are

combined into one test template. An example is the

template containing all the recommended measurements

for testing a current transformer.

The test template can be seen as a test plan. It tells the user

which measurements to make and provides the basis for

the overall test report.

Test templates can be prepared in advance in the office on

the PC – without the CPC 100 connected – and can then be

executed on site, step by step. Users can also create their

own test templates and define, which test cards they want

to include.

The settings and results of all manual tests can be stored

on a flash memory and transfered to a PC using a USB

memory stick or ethernet connection.

Customized reporting: Microsoft Excel™

After transferring the test results to a PC, report templates

in numerical and graphical form are available.

The measurement data – including settings and results as

well as administrative information such as date and time,

filename, etc. – can also be imported to these templates

for customized reporting, graphical result evaluation and

further analyses.

Microsoft Excel™ reports provide the basis for client-

specific reporting and allow test reports to be adapted to

utility or manufacturer specific formats. Further content,

such as company logos, can also be added.

Step by step through the test procedure with Primary Test ManagerTM

Managing location, asset and test data

PTM provides a well-structured database for managing

test results and getting a comprehensive overview of the

asset's condition. Locations, assets, jobs and reports can

be defined and managed quickly and easily.

Import and export functionality

PTM supports data exchange between different test

systems. Data can be imported easily in the PTM database.

In addition, they can be filtered or exported in common

formats (XML, PDF, Microsoft Word™, Microsoft Excel™).

Data synchronization and back-up

During on-site testing, data is often generated by multiple

testing teams. With the ‘PTM DataSync’ module all data

can be synchronized to a central database hosted on

premises or in the cloud. In doing so, data synchronization

and storage becomes safer and more convenient. The

relevant locations can be selected in order to keep the

local database small.

of tests on power transformers, circuit breakers,

and current transformers. It provides active

guidance for the user during the process of testing

with the CPC 100, making tests faster, easier, and

safer.

PTM supports in the best possible way during execution of diagnostic tests via

wiring diagrams and asset-specific test plans according to international standards.

Step by step through the test procedure with Primary Test ManagerTM

Executing diagnostic tests

PTM helps to define the test asset with specific nameplate

views. It indicates mandatory and recommended

parameters, making data entry fast and easy.

Based on the nameplate values, PTM generates a

customized test plan according to current standards and

guidelines for each asset. This way PTM is able to provide

you with a comprehensive test plan for assessing the

condition of your asset thoroughly.

Easy connection due to wiring diagrams

Pre-configured wiring diagrams based on selected assets

help to set up the CPC 100 correctly. This minimizes the

likelihood of measurement errors and speeds up the

testing process.

Result analysis and reporting

A real-time overview of the test results is given during the

measurement and an instant “pass/fail” assessment of

the test results is displayed based on specified limit values.

PTM automatically generates reports including all asset-

related information and the tests that have been performed.

This gives a comprehensive overview of the test object, test

results and assessment.

Comparison tools for detailed analysis

For a detailed analysis, different test results can be

compared side-by-side or trended over time. Users can

choose between a time- and type-based comparison

as well as a phase-based comparison.

Customized, individual reports

User can adapt reports to their needs in PTM. Reports can

be generated in Microsoft Word™, Microsoft Excel™ and

as a PDF file.

They can be further adapted by e.g. compiling the included

parts, providing comments or incorporating a company logo.

PTM supports in the best possible way during execution of diagnostic tests via

wiring diagrams and asset-specific test plans according to international standards.
