Electrical Faults: Causes, Analysis, Detection & Remedies

We regret to inform you that there are currently no scheduled sessions for this course, so please let us know your preferred date and location and we will contact you soon.

Course Introduction

This Electrical Faults training course teaches practical electrical troubleshooting and is concerned with the calculation of fault currents in electrical power systems. Short-circuit currents are associated with large amounts of very destructive energy and therefore calculations must be made to ensure that the short-circuit ratings of equipment are adequate to cater for these high currents. Accurate assessment of these currents is also essential for determining the settings of the system protection devices.

This training course includes the preparation of the system for analysis, by manual calculation and by the use of computer analysis. Participants will be introduced to the various fault analysis software programs.

This training course will feature:

  • Identification of causes of electrical faults
  • Understanding three phase short circuit currents
  • Recognition of unsymmetrical faults in transformers
  • Representation of unsymmetrical faults in a power system
  • Manual and software assisted of fault currents

Objectives

By the end of this training course, participants will be able to:

  • Understand the various types of fault currents
  • Determine the causes of overcurrent and short circuit current
  • Explain differences between symmetrical and unsymmetrical faults
  • Analyse the common faults in a power system
  • Interpret manual calculation verses software aided fault current calculations

Training Methodology

This training course will utilise a variety of proven adult training techniques to ensure maximum understanding, comprehension and retention of the information presented. This includes presentation and discussion of case studies (with appropriate solutions), latest videos, technologies, and various commercial fault current analysis software.

Questions are encouraged throughout, particularly at the daily wrap up sessions. This provides opportunities for participants to discuss with the Presenter specific issues and, if possible, find appropriate solutions. Specific goals of each participant will be discussed to ensure that their needs are fulfilled whenever practicable.

Who Should Attend?
