This Outdoor oil immersed 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.

It have been used in outdoor pole mounted and transmission line.
The voltage transformer made from outdoor high quality transformer oil, 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.

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).
