Fault Analysis in Power Systems

fault analysis in power systems

Usually, a power system operates under balanced conditions with all equipment’s carrying normal load currents and also the bus voltages inside the prescribed limits. This condition can be disrupted because of fault within the system. If the electrical fault current exceeds the interrupting rating of the protective device, the consequences can be devastating. It can be a serious threat to human life and is capable of causing injury, extensive equipment damage.

We just launched our Power Systems Engineering Vlog series and in this series, we are going to talk about all sorts of various power system engineering studies and commentary. We will overview the different blogs written by AllumiaX. It’s fun, it’s lively, it’s a video blog essentially and we hope that you’ll join us and benefit from it.

Types of Faults in Power System​

  1. Open Circuit Fault
  2. Short Circuit Fault

1. Open Circuit Fault:​

  • Open Conductor Fault
  • Two conductors Open Fault
  • Three conductors Open Fault
