Transformer Excitation Current Test - Engineering Home Page

Excitation Test Principal •When an AC Voltage Source, such as a Doble Test Set, is placed on a transformer, a small current will flow. •This small current is the Magnetizing Current: the current required to magnetize the Transformer core with the Magnetic Flux ∅

Transformer Failures, Causes & Impact

The Third category the faults are classified are on the basis of the detection [3] of the fault after it has occurred. This is an important part as after the fault is detected it can be repaired.
