BMC Training provides on 19 Sep 2021 Earthing, Bonding, Lightning and Surge Protection Of Electrical Systems and Equipment course [Electrical and Power Engineering Training] in London,UK

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. This 5 days course will discuss the different types of earthing systems in depth.

Course Objectives

  • 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
