GENERAL
This type of voltage transformer adopts epoxy-resin vacuum casting, assembled by 4 single-phase winding is applicable for power systems of rated frequency 50Hz or 60Hz and rated voltage up to and including 10kV, used for electric energy metering and voltage measurement. The product can effectively eliminate the frequency division, power frequency, and high-frequency resonance, will not be burned, and has a strong anti-ferromagnetic resonance and short circuit resistance.
It complies with the standards IEC61869 -1 & 3, GB 20840.1-2010
Instrument transformers-Part 1: General requirements, GB 20840.3-2013
Instrument transformers-Part3:Additional requirements for inductive voltage transformers, and
JJG 314-2010 Instrument Voltage Transformers.
