System Grounding & Protection
Neutral Grounding Resistors (NGRs) in Canada
Resistors that limit ground-fault current and protect equipment on resistance-grounded systems — stocked and shipped Canada-wide.
Purcee Industrial Power supplies neutral grounding resistors (NGRs) across Canada. We configure and ship NGRs for utilities, mining, industrial and generation systems that use resistance grounding, backed by full engineering support from our Foothills, Alberta head office.
An NGR limits the current that flows during a ground fault, protecting equipment, reducing arc-flash energy and allowing controlled fault detection. We help specify the resistor rating, let-through current and time rating to match your system.
Overview
What is a neutral grounding resistor?
A neutral grounding resistor (NGR) — also called a neutral earthing resistor — is connected between a transformer or generator neutral and ground to limit the current that flows during a phase-to-ground fault. By capping ground-fault current to a defined value, an NGR protects equipment, reduces arc-flash energy and mechanical stress, and supports selective fault detection.
NGRs are defined by the let-through current (commonly expressed in amperes), the system voltage and the time rating (for example 10 seconds or continuous). Resistance grounding is widely used on medium-voltage systems in mining, industry and generation. We help confirm the right rating for your application.

FAQ
Neutral Grounding Resistors — FAQ
What does a neutral grounding resistor do?
An NGR is connected between a transformer or generator neutral and ground to limit the current during a phase-to-ground fault. This protects equipment, reduces arc-flash energy and mechanical stress, and supports selective fault detection.
How is an NGR rated?
NGRs are defined by the let-through current (in amperes), the system voltage and the time rating, such as 10 seconds or continuous. Send us your system details and we'll confirm the rating.
Does Purcee supply NGRs across Canada?
Yes. We configure and ship neutral grounding resistors nationwide from our Foothills, Alberta head office, with delivery coordinated to your schedule.
How do I get an NGR quote in Canada?
Send your system voltage, required let-through current and time rating through our quote request form. Most quotes are returned within one business day.
Need a neutral grounding resistor?
Send us your system voltage and fault-current target — we'll spec the NGR and ship across Canada.
