Neutral Grounding Resistors
25,000 - 500,000 / Piece
1 Piece (MOQ)
The Neutral Grounding Resistors are generally employed in the LV and MV distribution networks to protect power transformers and generators from damaging currents in the event of earth fault. This protection system represents the best choice in terms of fast response to localize the fault and consequently to reduce and prevent the overheating and mechanical stress on the conductors.
Alternative protection systems like insulated neutral or direct earthing neutral have several and significant disadvantages such as dangerous transient over-voltages and high difficulties to localize the ground fault in the insulated systems or damaging fault currents with possible arc blast in the earthing neutral systems.
By inserting the Neutral Grounding Resistors with appropriate characteristics between the neutral point of the transformer and the ground it is possible to limit the ground fault current for a short time to allow a quick localization of the fault but, at the same time, it does not damage the equipment.
