Fault Current Analysis for Commercial Solar


Online Short Course

Fault currents can occur in grid-connected PV systems. They have the potential of causing significant damage to electrical system and are hazardous to life. As you move into commercial and industrial scale sites that have higher PV system power ratings, fault currents require more attention when developing the system.

As a result, Distribution Network Service Providers (or DNSPs) require short circuit studies to determine the significance of installing a PV system in their network.

This course will cover various topics including:

  • Fundamentals of fault currents
  • Fundamentals of protection devices and equipment
  • DNSP requirements
  • Calculating short circuit currents
  • Using software to analyse the fault current produced by a PV system on an existing network

Is this course for you?

This course was designed primarily with commercial and industrial (C&I) systems in mind. If you are looking to enter the solar C&I industry, this will be the perfect course for you to get an introduction to fault current analysis.

This course is eligible for 2 hours professional development with Engineers Australia.
