It is widely applied in insulation supervisory and detection of power plant, substation, communication system etc. DC systems as well as differential measurement of DC current, hole-through and isolated measurement of tiny current at the mA level. It is a key measuring part to make new DC insulation supervisory and detection equipment.
It has really actualized the goal of convenient, reliable, speedy, on-line, harmless DC current detection. Tt has more features such as minimum TD(temperature drift) , improved linear output value, ultra-loading capacity.
