RA871A Strong Electricity Invasion Detector is one of ROISCOK's great contributions. It makes up the blank of weak electricity protection system in this field. It takes advanced analytical elements of analog and digital signals to early-warn and protect the weak electricity system circuit. It is mostly applied to the communication cable of telecom, communications system of finance, railway, army, and electric power system, and so on. Working with the linked system of ROISCOK's control panel could automatically take relevant expeditious measures and ensure the related system to avoid the destruction from strong electricity and the fire breaking out.
