Comprehensive Power Transformer Preventive Maintenance

Course Duration: 2 Days

The 2-day course (16 hours) will focus on the Preventive Maintenance of Electrical Transformers. A basic understanding of a transformer and its construction will be discussed, and the theories of the electrical test to be performed. Proper procedures on testing will also be discussed on the first day. All procedures will be based on the InterNational Electrical Testing Association (NETA). On the second day, safety and testing procedures will be implemented before hands on training. Testing of power transformer will be performed.

Objectives: 

The objective of this seminar is to inform the participants of the importance of preventive maintenance of power transformers, its major components, and to guide them on the testing and evaluation of results of the power transformer.

At the end of the program, the participants will be able to: 

  • Explain different types of transformer
  • Know the major parts of a transformer
  • Discuss the nameplate data
  • Know the safety procedures in preventive maintenance of transformer
  • Discuss the electrical testing performed on transformers
  • Evaluate electrical test results gathered
  • Knowledge in present technologies in preventive maintenance of transformer
