Negative sequence current transmitterDetailed product description：

N3-AND AC negative sequence current transmitter is an instrument that can isolate the negative sequence current signal in the measured three-phase circuit and convert it into a DC voltage or current output proportional to the input negative sequence quantity. It is widely used in three-phase circuits of power systems and is equipped with corresponding indicator instruments or devices to measure negative sequence current. It can operate continuously for a long time.
