Project Description

This course is designed to provide participants a comprehensive and latest overview of transformer operation, maintenance, diagnosis & testing.  It covers the basic concepts of transformers as well as the main electric parameters and laws, magnetism and electromagnetism, Lenz and Faradays Laws, circuits, theory, the role of transformers in power systems, star and delta connections, standards, regulations and voltages as well as the various types and structure of transformers.

Why attend

This course introduces to an electrical engineer/technician and/or maintenance technician, complete transformer technology and terminology. It also discusses special transformers, transformer components, and materials, transformer cooling, transformer performance, electrical parameters and transformer faults. During the course, participants will be able to apply proper protection, operation and factory acceptance test (FAT), install, test and commission transformer and carryout transformer maintenance, routine inspections, diagnostic analysis, life expectancy and extension.

Course Objectives

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

  • Operate, maintain, troubleshoot and test power transformers in expert manner.

  • Deliberate the basic concepts of transformers, covering the main electric parameters and laws, magnetism and electromagnetism, Lenz and Faradays Laws, circuits, star and delta connections, theory, the role of transformers in power systems, standards, regulations and voltages.

  • Recognize the various types and construction of transformers.

  • Define special transformers as well as number transformer components and materials.

  • Regulate cooling of transformers, transformer performance and electrical parameters.

Who should attend

This course provides an overview of all significant aspects and considerations of transformers in accordance with the international standards for those who are involved in the sizing, selection, operation, inspection, maintenance and troubleshooting of transformers. This includes electrical engineers and electricians as well as other technical staff who need a sound understanding of power transformer operation, maintenance, troubleshooting or testing.
