Abstract

A novel electronic current transformer which can be integrated to disconnecting circuit breaker is put forward and manufactured firstly. Introduction is made to the principle

structure and tests about the product in this paper. This product use the LPCT sense measurement current signals

the air core coil sense protection current signals

the remote module sample the output signals of the LPCT and air core coil

the suspension fiber insulator ensure insulation and transmit signals. This product has the characteristics of simple insulation structure

small volume

light weight

high accuracy

large dynamic range

and good transient performance. Test results show that the key performances of the product

such as measurement accuracy

temperature cycle and anti-EMI

meet the network operational requirements. This product integrates with disconnecting circuit breaker

which can effectively reduce the substation area

will be used in Chinese new generation smart substation.
