Earthing Bonding, Lightning & Surge Protection of Electrical Systems and Equipment

Course Description

Earthling is an integral part of any electrical system. Properly selected earthing equipment will accomplish many desirable objectives, such as:

Improving the system operating characteristics.
Providing a source of earth fault current relaying.
Reducing personnel hazards.

Equipment earthing should be differentiated from system earthing since the functions of the two are often confused. A “system earth” is a connection to ground from one of the current carrying conductors of a distribution or wiring system. The return conductor for a line-to-neutral load on either single or multi phase systems is an example of such a current carrying conductor. This system ground may be made at such locations as transformer or generator neutral points by either a solid connection or through a current limiting device.

The primary purpose of the system earthing is related to operational characteristics and is an important, if not an essential part of the power system.

Course Objective

The basic principles & importance of earthing of electrical systems.
The function of power system earthing and the various options available.
Role of protective grounding in ensuring safety; sizing of grounding conductors.
Importance of equipotential bonding in ensuring safety.
Design of ground electrodes, measurement of soil resistivity and ground electrode resistance.
Fundamental principles in the design of grounding systems in substations.
Solving static electricity-related hazards by grounding and bonding.
Role of grounding in surge protection of power distribution equipment and sensitive systems.
How to test and maintain earth electrode & Earthing grid.

The Process

This course is designed to maximize delegate benefit from the outset. The goals of each participant are discussed to ensure their needs are fulfilled as far as possible. Questions are encouraged throughout particularly at the daily wrap up sessions. This provides opportunities for participants to discuss specific issues and if possible find appropriate solutions. Case studies are employed to highlight particular points and appropriate video material used to illustrate particular conditions. Some video tapes will support classes.
