Course overview:

This highly interactive training course will introduce you to the equipment that makes up an electric substation. It will explain how each type of equipment operates and guide you through the control and wiring diagrams that control equipment operation.

Recent technological developments have had a tremendous impact on all aspects of substation design, operation, maintenance, safety, and grounding, testing, and troubleshooting. A substation is a high–voltage electric system facility. It is used to switch generators, equipment, and circuits or lines in and out of a system. It is also used to change AC voltages from one level to another, and/or change alternating current to direct current or direct current to alternating current.

Knowledge of equipment conditions allows you to target your maintenance efforts to reduce equipment failures and improve substation reliability. Applying predictive maintenance methods can reduce your costs and improve the performance of your maintenance program.

 This course will show you methods and case studies that illustrate how to incorporate these new methods and testing techniques to improve reliability and optimize your existing maintenance program. You will study the latest testing technologies and how to apply them to determine the condition of the oil and gas-insulated transformers, circuit breakers, and other electrical equipment.

This course will feature:

  • Latest diagnostic testing techniques for assessing the condition of substation equipment such as transformers, circuit breakers, load tap changers, switches, and associated equipment
  • Application of predictive diagnostic testing to reduce equipment failures and extend equipment life
  • Aspects of safety as well as the practical and statutory issues
  • Maintaining, testing, and inspecting a proper grounding system for the electrical power substation

What are the Goals?

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

  • Design, install, commission, test, operate, control, and maintain HV/MV substations in a professional manner
  • Identify the various types of substations covering their parts, equipment, and major components
  • Recognize over current protection for phase and earth faults as well as the recommended grading intervals
  • Employ proper commissioning covering pre and cold commissioning, start-up, hot commissioning, the start of production, performance test, and acceptance of plant
  • Perform testing procedures and basic calculations
  • Illustrate medium voltage switchgear and oil circuit breakers

Who is this Course for?

  • Those who are involved in the design, installation, commissioning, maintenance, testing, control, and operation of electrical substation equipment
  • Industrial, utility, or plant engineers
  • Maintenance supervisors
  • Consulting engineers
  • Electric utility engineers

End of the workshop


While both In-House and Online training can present with cost-effectiveness and time-efficacy, there are some very specific differences between in-house courses and those based online.
The demand for additional courses by individuals or groups of people is increasing. Still, it depends entirely on the preferences of a person what type of training he or she wants to receive. Online courses and in-house training carry some similarities but they are considered to exhibit some very pivotal differences too. Despite that, both types of learning can be really beneficial for attendees.
