Electrical test equipment application solutions from Megger

Transformer turns ratio; checks the fundamental operational characteristic of a transformer, e.g., that it is transforming voltage as expected, and may help to identify short-circuited turns, open-circuited conditions, and incorrect winding connections. Exciting current; particularly adept in the detection of partial turn-to-turn short circuits in a winding (sensitive to the deterioration of the turn-to-turn insulation that is not tested in a power factor measurement). DC winding resistance; assesses the integrity of the current-carrying path between transformer bushing terminals; detects problems such as loose or defective connections, broken strands, open-circuit conditions, or high contact resistance in tap changers. Leakage reactance/short circuit impedance; the premier test to identify or confirm winding deformation.
