This manual contains a generalized overview of the fundamentals of transformer theory and operation.The transformer is one of the most reliable pieces of electrical distribution equipment (see figure l-l). Ithas no moving parts, requires minimal maintenance, and is capable of withstanding overloads, surges,faults, and physical abuse that may damage or destroy other items in the circuit. Often, the electrical event that burns up a motor, opens a circuit breaker, or blows a fuse has a subtle effect on the transformer. Although the transformer may continue to operate as before, repeat occurrences of such damaging electri- cal events, or lack of even minimal maintenance can greatly accelerate the evenhml failure of the trans- former. The fact that a transformer continues to oper- ate satisfactorily in spite of neglect and abuse is a tes- tament to its durability. However, this durability is no excuse for not providing the proper care.
