Switching & Protection´╗┐

Why are protection systems required and how are protection functions implemented? This course covers both technical and economic aspects of protection while providing an overview of the main concepts associated with the protection of distribution systems. Faults, methods of detecting and approach to isolating faults from the system are covered.

This course presents differences between UK, European, and North American distribution system practices and implications on protection system design.

Course content

This course will focus on these topics:

  • Why are protection systems required?
  • Power system performance during faults: voltage, current, fault level
  • Fault level calculations
  • Overview of system earthing and brief review of different earthing practices in different parts of the world
  • Economics and technical aspects and justification for protection
  • What is power system protection – components, types of protection
  • Performance parameters of any protection system: speed, discrimination, stability, etc.
  • Fault isolation: circuit breakers (interrupters), switches, sectionalizers, fuses
  • General protection scheme design, comprising sensors, signalling circuits, relays and circuit breakers.
