Gdva-404 Current Tansformer Ctpt Tester

GDVA-404 CTPT Tansformer Tester
I Introduction
GDVA-404 CT PT CTPT 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 GDVA-CT PT Analyzer include IEC60044-1, IEC60044-2, IEC60044-6 and C57.13
