MOA current monitor online monitoring system

Function introduction: MOA current monitor is mainly used for real-time and online monitoring of the full current, discharge current and cumulative action times of MOA arresters. The MOA current monitor adopts a current sampling method with no residual voltage and full isolation, which is mainly composed of a current transformer, A/D conversion, single-chip microcomputer and RS485 communication module. The current transformer is a single-turn primary through-core current transformer, and the measurement result is used The bus is used for transmission. The MOA current monitor adopts advanced compensation technology, so it has good versatility and interchangeable measurement.
