gfevt-c2-10_three_phase_electronic_voltage_transformer

INTRODUCE

GFEVT-C2-10 High accuracy Indoor voltage transformer is used for metering and relaying on less than 12kV circuits. The series electronic voltage sensors are made of epoxy resin casting, fully enclosed insulation, safe and reliable. They are suitable for installing common box outdoor pole mounted circuit breakers (ZW20) or outdoor pole mounted load switches (FZW28) with good anti condensation performance. They are suitable for zero sequence voltage measurement and protection in AC 50/60 Hz lines with a maximum voltage of 12 kV and below.
All of our indoor voltage transformers are strictly comply IEC60044-7, IEC 61869-6, ANSI/IEEE C57.13, GB1207-2006, GB/T 20840.6, GB/T 20840.7, GB/T 22071.2-2017, GB/T 20840.102-2020.
