10.5KV 48A Generator Neutral Grounding Resistance Complete Sets of Equipment
Brief introduction:
Neutral-Grounding Resistors (NGRs) are used to ground power systems by inserting a resistor between the system neutral and ground. This lowers the prospective ground-fault current to a predetermined value.
A properly designed resistance-grounded system provides benefits over both ungrounded and solidly grounded systems. Because the system is grounded, transient overvoltages do not occur and groundfault current can flow, allowing it to be detected and measured. Also,because a resistor is used to ground the system, the very large and destructive ground-fault currents of solidly grounded systems are absent. Ground-fault relays can be used on feeders to provide selective coordination and the ability to quickly locate or isolate the fault.
Applications:
Resistance grounding is typically applied on transformers and generators where safety and continuity of service are important. A faulted feeder may remain in operation until it is safe to repair the fault, where allowed by the local electrical code.
