An online intensive professional development training course on

Electrical Substation Design,
and Commissioning Procedure

Electrical Equipment, Design, Sizing and Earthing

Why Choose this Online Training Course?

This Electrical Substation Design, Testing and Commissioning Procedure online 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 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 condition 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 AZTech training 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 oil and gas insulated transformers, circuit breakers, and other electrical equipment. Electrical substation safety is an important issue in utility networks as well as large industrial installations and requires adequate attention in the stages of system planning, design, installation, operation and maintenance. In this training course, we will take a look at the theoretical aspects of safety as well as the practical and statutory issues.

This online training 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 inspection a proper grounding system for the electrical power substation

What are the Goals?

By the end of this online training course, 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 its 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, start of production, performance test and acceptance of plant
  • Perform testing procedures and basic calculations
  • Illustrate medium voltage switchgear and oil circuit breakers
