Neutral Grounding Resistors
In the absence of ground faults, all Ungrounded, Resistance Grounded and Solid Grounded systems are reliable and safe, but ground faults are a reality in any electrical system and so the question is what is the risk associated with your electrical system?
While High Resistance Grounding is the safest approach to grounding a power system, some applications may remain ungrounded (for legacy reasons) or solidly grounded. I-Gard has the products to cover all applications.
