GDVA-404 Current Transformer Testing and Potential Transformer Testing Set
Introduction:
GDVA-404 CT PT Analyzeris 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 byGDVA-CT PT Analyzerinclude IEC60044-1, IEC60044-2, IEC60044-6 and C57.13
