Overview

Grounding, EMI and Power Quality

Course Description

In the Grounding, EMI, and Power Quality course, you will get a comprehensive overview of design practices for grounding and electromagnetic compatibility of industrial, commercial, and residential systems. This includes linear and distorting loads, fundamental principles of grounding and protection practices of electric power installations, the 2005 NEC Article 250 and other related standards, and the fundamental principles of power-system electromagnetic influence and practices. You will walk away with a solid understanding of power-quality issues and know all of the capabilities of the Grounding and ElectroMagnetic Interference (GEMI) software.
