THE COURSE

Few topics generate as much controversy and argument as that of grounding or earthing and the associated topics of lightning and surge protection of electrical and electronic systems. Any engineer dealing with power supply networks needs to understand the basic principles of grounding system design and its role in ensuring safety of equipment and personnel. A correct understanding of the basic principles involved will help to avoid mistakes in grounding system design, mistakes that could lead to expensive failures and long downtime.

In this course, we will try to demystify the concepts of grounding as applicable to utility networks and industrial plant distribution systems as well as their associated control equipment. In fact, a lot of myths have been built around this subject, although it is quite a simple one when approached from basic principles. Our endeavour will therefore be to explain the fundamentals of grounding, which we hope will enable the participants to gain a correct perspective of the subject and give them the knowledge needed to solve real life grounding problems.
