Power System Protection: Part One

This course provides an essential introduction to the principles of power system protection. Covering the fundamental role of protection, key components including fuses and relays, their principles of operation the course goes on to provide an enlightening introduction to grading principles and basic fault calculations. The course includes practical exercises and a ‘walk through’ the LV and HV system.

It provides a very detailed introduction to essential protection principles at a level that does not require knowledge of complex numbers. It is designed to lead on to the Power Systems Protection: Part Two course which takes delegates on to protection theory, practice and calculations at a level that does involve complex numbers.

  • Understand why protection is critical on electrical networks
  • Develop an understanding of protection systems for power assets
  • Understand the role of protection in network design
  • Develop an understanding of fault calculations
  • Be able to apply learnt skills directly in your place of work
  • Understand safety requirements in power network protection
