QUT EEP205 Power System Fault Calculation

21 March 2018 - 23 March 2018
8:30 am - 5:00 pm
The Terrace Conference Centre
114 The Terrace


The power system fault calculations course provides the necessary basis for assessing fault current levels in any electrical power network. In order to achieve this every plant item in the network is modelled from its own characteristics. Fault calculations are determined from the solution of appropriate networks obtained from these plant model building blocks. Different fault types have their own methodology in deriving the sequence currents and voltages occurring in power system from which the phase currents and voltages can be determined.

Course Aims

The module will give the user the ability to determine fault current and voltage values for use in the many aspects of electrical system design and performance such as in the specification of the ratings of plant and equipment, in the sesign of earthing layouts and in the setting of electrical protection relays.

Objectives and Outcomes

On completion of this course participants will have an understanding of the:

  • Use per unit quantities for fault analysis
  • Demonstrate how sequence voltages, currents and impedances are used
  • Determine the correct positive, negative and zero sequence models in per unit quantities
  • Calculate fault currents at any point in an electrical network for:
    • Phase to Ground Faults
    • Phase to Phase Faults
    • 3 Phase Faults
  • Calculate the network contribution of fault and sequence currents
  • Determine phase currents from sequence currents with or without transformer vector shifts involved
  • Determine the impact of effective earthing and current decay on fault currents
