Maximum efficiency, reliability and longevity of electrical equipment such as the various types of motors, variable-speed drives, transformers, generators, rectifiers, inverters, uninterruptible power systems, circuit breakers, fuses, and power station electrical and protective systems are of great concern to many industries. These objectives can only be achieved by understanding the characteristics, selection criteria, common problems and repair techniques, preventive and predictive maintenance.

This Electrical Equipment Troubleshooting & Maintenance training course provides the latest technology in the troubleshooting and maintenance of electrical equipment.   It also explains how these equipments operate and provides guidelines and rules that must be followed for a successful operation. Their basic design, operating characteristics, specification, selection criteria, as well as all maintenance issues too are covered in detail.


The important features of the Electrical Equipment Troubleshooting & Maintenance training course are:

  • Troubleshooting and dealing effectively with emergency situations
  • Implementing the best electrical maintenance management system


  • Comprehend the hazards when working with electrical power systems.
  • Perform electrical switching operations safely on all switchgears and associated equipment in preparation for maintenance tasks.
  • Understand the correct methodology and safe operation when working on electrical equipment, switchgear on electrical distribution systems and all of the associated electrical plant and to be aware of all the associated hazards.
  • Understand diagnostic testing and inspection, advanced fault detection techniques, critical components, and common failure modes.
  • Study selection criteria, commissioning requirements, predictive and preventive maintenance, reliability, testing and cost.
  • Discover the maintenance required to minimize their operating cost and maximize their efficiency, reliability and longevity.


The Electrical Equipment Troubleshooting & Maintenance training course is targeted at both developing engineers & experienced electrical personnel working within commercial and heavy industrial environments within oil and gas processing plants. The training course provides personnel with the knowledge and competence to perform quality maintenance, installation, testing and inspection of generic electrical plant & equipment.


The Electrical Equipment Troubleshooting & Maintenance training course is designed to have an interactive format, to maximize delegate participation. Questions and answers are encouraged throughout and at the daily roundup sessions. Needs-Based case studies and examples will be introduced and discussed, in problem-solving workshop sessions.

Pre & Post course assessments will be used to measure the effectiveness of this training.
