Portable Current Transformer Test Set

Model: CTP-200P

The Portable Current Transformer Test Set CTP-200P is designed to automatically measure the related parameters of current transformer(CT), such as excitation characteristic, turns ratio, polarity, winding resistance, saturated and unsaturated inductivity, remanence flux percentage, accuracy limiting factor(ALF) or instrument security factor(FS), secondary burden etc.

The CTP-200P also allows the simulation of ratio, secondary time constant, ALF and FS at free adjustable burden and primary current also after the test with the determined test results.

The Portable Current Transformer Test Set CTP-200P also supports voltage transformer(VT) test. The ratio, polarity, excitation characteristic and winding resistance of VT can be tested.

The Portable Current Transformer Test Set CTP-200P is rugged and immune to electrical noise interference in high voltage substations.
