Neutral Grounding Resistors
IPC Neutral Grounding Resistors are designed, rated, manufactured and tested in strict compliance with IEEE-32
Neutral Grounding Resistors are used for resistance grounding of industrial power systems. They are usually connected between earth ground and the neutral of power transformers, power generators or artificial neutral transformers. Their main purpose is to limit the maximum fault current to a value which will not damage generating, distribution or other associated equipment in the power system, yet allow sufficient flow of fault current to operate protective relays to clear the fault.

SPECIFICATION

Neutral Grounding Resistors are rated in line-to-neutral volts, initial current in amps and allowable "on" time. They must be capable of carrying rated current for the allowable on time without exceeding the allowable temperature rise established by IEEE standard 32-1972. All

IPC Neutral Grounding Resistors are designed, rated, manufactured and tested in strict compliance with IEEE-32.
IPC low voltage grounding resistors (up to 347 volts) are

CSA approved up to 5 amps continuous and medium voltage (1390 and 2400 volts) are approved up to 10 amps.

CSA APPROVED GROUNDING RESISTORS

To meet CSA outdoor requirements, we supply solid side covers and an elevated hooded roof for maximum ventilation.

Low voltage CSA enclosures feature an external terminal junction box for easy field connection.
