the secondary circuit, check the characteristics of the
transformer, verify the action value of the circuit breaker trip
mechanism and measure the opening and closing time of the circuit
breaker.
Under the control of high-performance single-chip microcomputer,
the relay protection calibrator has the characteristics of high
precision, full function, stable performance, simple operation and
flexible movement.
Main Features
