THE COURSE

This online course has been designed to give plant operators, electricians, field technicians and engineers a better appreciation of the role played by power system protection systems. An understanding of power systems along with correct management will increase your plant efficiency and performance as well as increasing safety for all concerned.

The course is designed to provide excellent understanding on both a theoretical and practical level. Starting at a basic level and then moving onto more detailed applications, it features an introduction covering the need for protection, fault types and their effects, simple calculations of short circuit currents and system earthing. This course includes some practical discussion on simple fault calculations, relay settings and the checking of a current transformer magnetisation curve.

 

YOU WILL LEARN HOW TO:

  • Describe the fundamentals of electrical power protection 
  • Identify and understand the different fault types
  • Perform simple fault and design calculations 
  • Basically  specify and use protection system components – CTs, VTs, CBs, fuses and relays 
  • Apply relay settings; check, test and assess current transformers
  • Demonstrate a fundamental knowledge of different applications in protection

WHAT’S INCLUDED?

  • Four 50 minute live, practical sessions with your instructor and attendees 
  • The full technical eBook manual for “Practical Power System Protection” which includes course slides, cases studies, calculations and practical exercises
  • Four hours of additional in-depth video sessions covering many additional areas – yours to keep and watch at your convenience

 

WHO SHOULD ATTEND?

  • Design engineers
  • Electrical engineers
  • Electrical technicians
  • Electricians
  • Field technicians
  • Instrumentation and design engineers
  • Plant operators
  • Project engineers

PRE-REQUISITES:
Fundamental knowledge of electrical engineering.
