Applications, Understanding Grounding and Bonding of Electrical Systems


Course Description

This course will focus on the purpose for grounding and understanding of the grounding systems.  We will examine the different types of grounding systems.  We will review grounding electrodes, types, the measurement of earth grounding electrodes, and function of the electrodes.  We will evaluate grounding for fault protection, signal reference, lightning protection and safety.  In grounding we will discuss equipotential plane, bonding, single point grounding along with stray voltage, sources, and mitigation for stray voltage.

Course Objectives

This course should help the qualified individual understand different types of grounding system and how they function in these electrical systems.  We will review and understanding the function of grounding electrodes and measurement of these electrodes as referenced to earth. Qualified individuals will understand grounding for fault protection, reference or signal reference, lightning protection and touch potential with focus on safety.  The class participants will be taught how to identify stray voltage sources and understand the use of epuipotential plane as referenced in Article 680 of the NEC.  Participates will review grounding in communication networks of signaling, video, data, and alarm systems as referenced in Chapter 8 the 800 sections in the NEC of these rules for the proper operation of communication systems with the electrical system.
