Transformer/Generator Neutral Point Protecting Neutral
Grounding Resistor/Neutral Earthing Resistor Product
DescriptionWhy Use a Neutral Grounding Resistor in the power supply
system?First, let us introduce what is a neutral grounding resistor
and the function of it.A neutral grounding resistor is composed of
enclosure, resistors, disconnecting switch, CT, heater,
lightning arrester, etc. The primary purpose of a Neutral Grounding
Resistor (NGR) is to limit the fault current already present in a
single line to ground fault. That is why NGRs are mostly employed
in low and medium voltage (LV and MV) distribution networks to
ensure generators and transformers remain protected from damaging
currents in the event of an earth fault. Fullde Electric
has own R&D team and factory to produce various NGRs for
customers. Detailed Photos Product
