For an efficient power transmission and distribution it is imperative that the used high voltage equipment operate at their maximum load without sustaining any malfunctions. Especially transformers, which are needed at the junctions of energy supply systems, have an exposed importance due to the widespread negative consequences resulting out of a failure.
