About This Product

This is a device installed at power generation and substations that protects the power system by isolating and localizing (preventing the spread of) the accident location when a short circuit or ground fault occurs in the power system. ■Product features ・Uses a high-performance CPU in the relay unit, saving space (1/3 compared to conventional models) ・Easy to secure space for new installations and renewal of existing ones, contributing to significant process reduction and efficiency improvement ・Relay information can be checked remotely by browsing the browser. ・Early detection of failures through wide-area constant monitoring and automatic inspection ・Low power consumption (less than 1/2 compared to conventional) ■Applicable location The basic system conditions for the 66kV extinction reactor system (PC+NGR) and resistance grounding system (NGR) are as follows. ・Fundamental wave component (50Hz): 31kA at maximum fault current ・Ground fault current: NGR rating 100 to 1,500A
