General
This outdoor epoxy resin type combined current transformer/voltage transformer metering instrument transformer (metering units, MOF), used in current transformer used in 3.3kV, 6kV, 10kV, 11kV, 12.5kV and 13.8kV power system, for measuring energy, power line protection, and control.
It have been used in outdoor pole mounted and transmission line.
The voltage transformer made from outdoor high quality ultraviolet-proof epoxy resin, high quality CRGO core for metering, primary and secondary use pure electrolytic copper, both winding and core have shielding processing.
This combined instrument transformer, can combined from 2 Current transformer and 2 voltage transformer to be 3 phase 3 wire, also can combined from 3 current transformer and 3 voltage transformer to be 3 phase 4 wire.
2 voltage transformer structure use V/V connection, 3 voltage transformer structure use Y/Y connection.
Outdoor vacuum circuit breaker can work as recloser, automatic protection, metering with smart prepaid meter, if no money one prepaid meter, MV power line automatic cut down, if charge money on prepaid meter, power automatic power recovery.
It has default phase protection, overcurrent protection, overvoltage protection, and other relay protection functions.
Standards
All UNISUN Electric instrument transformers are in conformity with IEC standards, and recommendations IEC 61869. Transformers in conformity with specific country standards can also be supplied. (IEEE C57.13, NBR6855).
All vacuun circuit breakers conform to the IEC 62271-100, CEI – VDE – BS Standards are equivalent to IECStandards due to harmonization with IEC
