BMC Training provides on 21 Nov 2021 Earthling Of Utility and Industrial Distribution System course [Electrical and Power Engineering Training] in Kuala Lumpur,Malaysia

Course Description

Few topics generate as much controversy and argument as that of grounding (or earthing as it is called in some countries) 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 him/her to avoid mistakes in grounding system design, mistakes that could lead to expensive failures and long downtime. In this workshop, we will 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 you to gain a correct perspective of the subject and give them the knowledge needed to solve real life grounding problems. Essentially this course is broken down into System Grounding, Protective grounding and Surge/noise protection of power and electronics systems normally found in distribution networks. A brief introduction to the design of substation grounding has been included. Detailed information on ground electrodes and measurement of ground resistance is also available.
