Why Choose this Training Course?

Motor protection methods and relays are one of the most crucial and important component in every electrical system. This course attempts to answer the many questions in an electrical engineer’s mind by describing the various concepts of motor system protection. The scope includes all the main components and types of protection schemes and causes of faults and failures in motor installation.

The need for electrical power system requirements for reliability and efficiency of operations and precise protection is of paramount importance

Selection and identifying the various types of motor protection relays and causes of faults are of equal importance.

What are the Goals?

Delegates will gain a detailed appreciation of the following:

  • To understand the principles of operation of various types of motors and control gears
  • To identify the types of motor casings that can prevent accidents and malfunctions of a motor installation due to external influences
  • Obtain a reasonable understanding of motor inner workings and what can go wrong should the motor/drive malfunction.
  • Will understand the principle components of the different types of motors protection relays
  • The selection of the various types of motors in relation to short circuit faults
  • Will understand the basic components in relation to inspection and testing of the various types of motor

How will this Training Course be Presented?

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 materials used to illustrate particular conditions.
