Maintenance and Inspection of Transformers
Course Description
Transformers are static electrical devices that transfer energy between electrical circuits through electromagnetic induction. They play a pivotal role in the transmission and distribution of electrical power, enabling the efficient movement of electricity from generation stations to industrial, commercial, and residential users. Proper maintenance ensures minimal energy loss, system reliability, and safety. Understanding their principles and construction forms the foundation for all subsequent inspection and maintenance procedures.
