MOA current monitor (JC-OM200/A)
The arrester monitoring device is mainly used for real-time and online monitoring of the full current, discharge current and cumulative action times of MOA arresters. The arrester monitoring device 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 uses a single-turn primary core-through current transformer, and the measurement result is used on a bus To transfer. The arrester monitoring device adopts advanced compensation technology, so it has good versatility and interchangeable measurement.
