MRD-FD type neutral grounding resistorcabinet is complete equipment specially used by generators in power plant whichadopts high-resistance grounding for neutral. The voltage grade for generatormainly ranges from 6KV to 20KV. When one point of the stator grounds, thedevice is able to limit the grounding current at a reasonable value, andeffectively restraint arc flash transient overvoltage associated withsingle-phase grounding.
