This outdoor epoxy resin type combined TC TP, metering instrument transformer (metering units, MOF), used in  current transformer used in 15kV, 17.5kV, 20kV, 22kV and 24kV power system, for measuring energy.

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.


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).
