Power Quality & Grounding

Go with the Power Flow

The importance of load studies BY KATHLEEN WOLF-DAVIS with CASY HENRY, Megger If you’re running an industrial power system—whether for an airport, a mill, a factory or a smelter—you’re focused on more than the traditional utility concept of keeping the lights on. You definitely need that...

INSULATION RESISTANCE TEST

Insulation Resistance (IR) test, often called Megger test, is more than 100 years old and assumed to be a very straightforward test. During my inspection and testing work in the past 15 years in Canada, US, and internationally, I have seen different practices of performing and interpretation of IR...

The Art of Ground Testing
