Electrical Power, Control Systems & Power Plant Operators


Earthing Bonding, Lightning & Surge Protection Of Electrical Systems And Equipment


  REF: EE163  DATES: 16 - 20 Jul 2018  (One Week)  VENUE: Malaysia (Kuala Lumpur)-Grand Millenium Hotel

Overview:

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.

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.
