Neutral earthing resistors limit the fault current that would flow through the neutral point of a transformer or generator in the event of an earth fault
as per reference standard IEEE C57.32a.
NEUTRAL EARTHING RESISTOR
The following technical data are required for design of a neutral earthing resistor:
Operating voltage
Fault current
Fault duration (normally 10 or 30 seconds)
Our neutral earthing resistors are manufactured as follows:
Compliance with IEEE C57.32a.
High temperature stainless steel alloy used as a resistor element material.
Protection class: IP21 – IP55.
Inclusion of additional components (e.g. current transformers & Earthing transformer)
