I Introduction
This current transformer CT PT testing
equipment is performing excitation, ratio and phase error, polarity, secondary loop burden and coil resistance on current and voltage transformer. The instrument provides fully
automatic testing and calibration for all types of low leakage flux current transformer and inductive voltage transformer. The maximum knee point voltage of sample CT could be reached
8.4kv.
The standards support by CTPT Transformer Analyzer include IEC60044-1, IEC60044-2, IEC60044-6 and C57.13
