GDVA-404 CT PT  Tester/  Current and Potential Transformer Tester

Product Description

 I Introduction 

This CT PT  tester/  current and potential transformer tester 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 ct pt tester include IEC60044-1, IEC60044-2, IEC60044-6 and C57.13
