The Unsung Hero: knowing the Importance of Neutral Grounding Resistors
ahead of diving to the specifics of brands, it's very important to appreciate the perform of a Neutral Grounding Resistor. In a few-section electrical devices, the neutral level of a transformer or generator might be connected to ground straight (solidly grounded), by an impedance (like an NGR), or left ungrounded. Ungrounded devices can result in transient overvoltages throughout a fault, whilst solidly grounded programs can knowledge particularly substantial fault currents.
A Neutral Grounding Resistor provides a well balanced solution. Its Key operate will be to limit the bottom fault present to a predetermined, Protected degree. This controlled present-day:
Prevents products destruction: lowers the thermal and mechanical stresses on transformers, turbines, switchgear, and cables during a fault.
