BH-0.66-50 Current Transformers

The BH-0.66-50 current transformers are precision instruments designed for accurate measurement and monitoring of electrical currents in various industrial applications. With a rated current of 50A and a transformation ratio of 0.66, these transformers provide reliable and precise current measurement capabilities.

Indoor epoxy resin current transformer or indoor plastic casing current transformer

• Single phase, two phase or three phase.

• Rated voltage: 0.66kV

• Metering class for CT: 0.2S, 0.2,0.5, 0.5S

• Standard: IEC61869-2

• Type name: BH-0.66-50

This indoor dry type current transformer is used in 0.66kV, 0.75kV. power system, for measuring and protection.

It has been used in cubicle switchgear or in bay-installed switching stations.

The current transformer is made from high temperature indoor epoxy resin, amorphous alloy core for metering and high quality inside core for protection, primary and secondary use pure electrolytic copper.
