Description

This course covers the theory, operation, maintenance and testing of power transformers and auxiliary equipment. Topics included are transformer fundamentals, transformer ratings, transformer cooling, nitrogen gas systems and insulation systems. The source concludes with in-depth discussions on transformer testing techniques. This course is applicable to technicians and engineers who need a sound understanding of power transformer operation and maintenance.

Participants will learn safe and proper maintenance and testing procedures on pad-mounted, power transformers. The course covers transformers used in commercial and industrial power distribution systems, including oil and dry-type units. Larger power transformers used in utility applications are also covered.

Load and no-load tap changer maintenance, ac and dc testing, routine inspections and oil sampling and testing are covered in detail. Participants will learn how to perform routine oil tests, and understand how to perform the major tests that are required. A variety of electrical test equipment from various manufacturer’s will be discussed.

 

Course

Upon completion of this course, the participant should be able to:

•  Explain the basic operation of a transformer.
• Discuss turns ratios and calculate terminal voltage and current.
•   Discuss terminal markings and various single phase and three phase wiring schemes. (WYE vs DELTA).
• Explain how to perform a polarity test on a potential transformer.
•  Discuss the electrical testing performed on transformers such as insulation resistance testing, excitation and power factor testing.
• Discuss the various tests performed on insulating
