This outdoor epoxy type combined instrument transformer (metering units, MOF) used in 13.8kV, 15kV, 20kV power system, for energy measuring.
It have been used in outdoor pole mounted and transmission line.
The voltage transformer made from outdoor high quality 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. all in one body structure, in powder coating steel tank and using porcelain bushing.
2 voltage transformer structure use V/V connection, 3 voltage transformer structure use Y/Y connection.
All SAGHU Electric instrument transformers are in conformity with IEC standards, and recommendations IEC 60044-1. Transformers in conformity with specific country standards can also be supplied. (IEEE C57.13, NBR6855).
