Resin cast current transformers are available for metering and protection application. These current transformers are mainly fabricated according to client’s specification. Ct coils are encapsulated in cast resin (polyester / epoxy). Secondary terminals are provided with either screws or studs. The main insulation between primary and secondary and earth is obtained by this epoxy resin. These transformers are of compact design with high mechanical and electrical properties. These are non-hygroscopic and hence give very good insulation properties even in given humid conditions.

We manufacture highly efficient and accurate resin cast potential transformers. These resin cast potential transformers are used in ac circuits, for the purpose of measuring large voltages. Their main function is to reduce the supply voltage to a small value so that it can be easily measured with standard low range ac instruments of moderate size and capacity. There are many advantages of using resin cast potential transformers for range extension of ac meters. We also offer resin cast potential transformers of dual purpose metering & protection that are also commonly used.
