Power System Protection: Part One

This course provides an essential introduction to the principles of power system protection. It covers the role of protection, why it is required, components of protection systems and their principles of operation. It goes on to provide an understanding of basic protection theory, grading principles and fault calculations. The course includes practical exercises and builds a fundamental understanding of protective systems on electrical networks from LV up to 132kV.

By attending the course, you will gain an understanding of:

  • Legislative and safety requirements
  • The role of protection in network design
  • Components of protection systems
  • Relay types and principles of operation
  • Grading principles
  • Basic fault calculations
  • Principles of LV and HV network protection
  • LV electronic relay principles and settings

Programme may be subject to amendment.

This course is designed for engineers and technicians in roles which require an understanding of the principles of power system protection, as well as those working specifically in protection disciplines. It will be of benefit to people working in commissioning, testing, operational and maintenance roles.

As it provides a sound underpinning knowledge it will also be beneficial to the development of new engineers, managers and supervisors and people working in Network Design and Asset Management roles.

The follow-on course, Power Systems Protection: Part Two, is designed for a more specialised audience and takes delegates through protection theory, practice and fault calculations at a level that involves complex numbers.

Recent delegates who have attended this course include:

  • Authorised Electrical Engineers
  • Asset Managers
  • Commissioning Engineers
  • Design Engineers
  • Electrical Engineers
  • Electrical Maintenance Planners
  • Electrification & Plant Engineers
  • Graduate Engineers
  • High Voltage Engineers
  • Project Engineers
  • I&E Technicians
  • I&E Engineers / Supervisors
  • Power & Distribution Engineers
  • Protection and Commissioning Technicians
  • Senior Electrical Engineers
  • Service Electricians
  • Utilities Commissioning Team Leaders
  • Wind Farm Managers
