I Power Transformer CT Test Introduction 

This IEC60044 Power Transformer CT Test  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 IEC60044 Power Transformer CT Test include IEC60044-1, IEC60044-2, IEC60044-6 and C57.13
