technical maintenance engineer from a medium-sized steel mill contacted us last spring regarding an unprecedented issue: a 1600 kVA distribution transformer that works perfectly when voltages at the factory floor are sufficient gets reported as being in violation of operational standards. The root cause was not found in either the tap changer or the protection relay; it was hidden away in the working principle of the transformer, that is electromagnetic induction, which allows any transformer to operate. Once our experts found out how to correlate induced voltage and turns, the solution, that is making a ratio adjustment, took hours.
