50/60Hz Current Instrument Transformer Test Set Maximum Knee Voltage 40kV

Model: CTP-120PA

Automatic Instrument Transformer Test Set CTP-120PA is a portable and
multifunctional test kit for testing both current transformers and voltage
transformers in their equipment configuration, such as being mounted in
transformers, oil circuit breakers or switchgear. It is necessary for the
equipment to be completely isolated from the electrical system.

With a one-click button, the CTP-120PA performs a CT saturation test and
calculates the rated knee point in compliance with either IEEE C57.13.1, IEC
60044-1, IEC 60044-6 or IEC 61869 on both standards as well as of specialized
CTs such as PX, TPS, TPX, TPY and TPZ. The saturation test can test knee point
up to 40 kV. This allows testing even the larger generation class CT with a
portable instrument.

Many substations CTs include a multi-ratio secondary, therefore the CTP-120PA
has the ability to plot and simultaneously display up to 6 CT saturation
curves.

As part of a regular maintenance program to verify factory readings and locate
the presence of defects in voltage transformers, the CTP-120PA can accurately
measure the ratio, polarity, excitation characteristic and secondary winding
resistance.
