N3-AND AC negative sequence Current transducer
Quick Overview
The AC negative sequence current transmitter is an instrument capable of isolating and amplifying a negative sequence current signal in a three-phase circuit into a DC voltage or current which is linearly proportional to the input negative sequence quantity, and is widely used in a power system.
