Transformer Test Set – Multi-functional primary test system for substation commissioning and maintenance.

The patented test system replaces numerous individual testing devices and offers new, innovative testing methods. This makes testing with the CPC 100 a time-saving and cost effective alternative for conventional testing methods. Despite its expansive capabilities, the CPC 100 is very simple to use.

Using the CPC 100, electrical tests on various assets can be performed:

>> Current transformers

>> Voltage transformers

>> Power transformers

>> Power lines

>> High-voltage (HV) cables

>> Grounding systems

>> Rotating machines

>> GIS systems

>> Switchgear and circuit breakers

>> IEC 61850 installations

>> Protection relays

With the CPC 100 power transformers and their ancillary components can be tested:

>> Windings

>> Tap changer

>> Bushings

>> Insulation

>> Core

>> Connection leads

>> Surge arrestors

 

Applications

Current transformers (CT)  Ratio, burden and polarity Phase and magnitude error Excitation curve Winding resistance Secondary burden Dielectric withstand voltage (2kV AC) CT circuit continuity	Voltage transformers (VT)  Ratio, burden and polarity Phase and magnitude error Excitation curve Winding resistance Secondary burden Dielectric withstand voltage (2kV AC) VT circuit continuity
Transformers  Ratio Winding resistance Tap changer test Excitation current Short circuit impedance	Lines and cables   Impedance (k-factor) Transformer coupling
Grounding systems  Ground impedance Step and touch voltages	Circuit breakers  Contact resistance

 

The powerful testing device provides up to 800 A or 2 kV with up to 5 kVA over a frequency range of 15 to 400 Hz or 400 A DC while its compact design (29 kg / 64 lbs) makes it easy to transport and ideal for on-site testing.

The CPC 100’s variable output frequency allows the use of test frequencies different from the mains frequency offering a very effective suppression of mains-related interference. Thus the CPC 100 is able to obtain very accurate results even in extremely noisy environments.
