Electrical
Transformer Testing and Maintenance
This training will be 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.
Students
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. Students 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.
