This indoor epoxy resin type voltage transformer used in 15kV, 17.5kV, 20kV, 22kV and 24kV power system, for measuring and protection. Phase to grounding voltage transformer with R3 of primary system voltage.
It have been used in cubicle switchgear or in bay-installed switching stations.
Both phase to phase voltage transformer and phase to grounding voltage transformer are made from high temperature indoor epoxy resin, high quality CRGO core for metering and protection, primary and secondary use pure electrolytic copper, both winding and core have shielding processing.
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).
