Introduction
GDVA404 is unique multifunction instrument designed to meet the IEC60044-1, IEC60044-2, IEC60044-6 and C57.13 standards for performing excitation, ratio and phase error, polarity, secondary loop burden and coil resistance on current or 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 byGDVA404 include IEC60044-1,IEC60044-2, IEC60044-6 and C57.13
