Consider all site parameters before recommending an IG system. But first, measure existing equipment grounding system's impedance with a ground impedance tester prior to making any changes to the grounding system....More
Should You connect Transformer Ground to Building Ground? Q. What are good transformer grounding techniques? I would especially like to know about connecting...More
Generator grounding errors can cause current flow in de-energized circuits. This can cause nuisance tripping of protective circuits, with costly and possibly lethal results....More
Verification of shield performance under ground-fault conditions will prevent systemwide cable damage.As we all know, the metallic shielding in a medium...More
To ensure your electrical system functions properly, it's important your buried ground system has low impedance. So how do you achieve this goal while keeping safety in mind?...More
Alert the OEM of possible shock hazards, lightning damage, ground loop currents, and electrolysis in your facility. If you find its "required" ground rod causes such problems, ask the OEM to accept liability in writing....More
Do grounding electrodes end at the building wall, or do they continue on into the building? How does that affect the application of other Code rules?Code...More
A properly designed and installed grounding system ensures reliable performance of electrical substations.Just how important is substation reliability?...More
The new paragraph in Sec. 250-80(a) creates questions about the relationship between water piping and separately derived system grounding.One of the most...More
This standard seeks to bring order to the apparent chaos of power quality assurance by describing recommended practices for powering and grounding sensitive...More

Efforts to ensure continuity of power must not create potential hazards through improper grounding techniques.Remote pumping stations, each with their...More
These answers are given by our panel of experts. I am chairing this panel, and the other panel members include Bill Summers, James Stallcup, and Dan Leaf....More
Your choice of SRG depends on knowing what's legitimately true and patently false about grounding, bonding, and electrical noise mitigation.Proper bonding...More
Your choice of either solid, low-, or high-resistance grounding is based on the power system application and degree of power interruption tolerated.Solid,...More
LEDs have unique and compelling characteristics that make them ideal for industrial lighting applications. But there are a variety of misconceptions about LEDs, how well they work, how long they last, and more. Digital Lumens developed this whitepaper to dish up the facts around LEDs and address some common misunderstandings....More
An arc flash is associated with the explosive release of energy caused by an electrical arc, due to either a phase-to-ground or a phase-to-phase fault. This kind of fault can result from many factors – a dropped tool, accidental contact with electrical systems, buildup of conductive dust, corrosion or improper work conditions.....More
Abstract: In this webinar, Mike will not only explain the current NEC requirements for GFCIs and AFCIs, but he'll explain how they operate, what causes their premature failure, and when they won't provide the safety protection you might have thought they would.
Abstract: This webinar will teach attendees the difference between risk and hazard, and how the choice of system grounding has a direct impact on reliability and safety.
