WebIn three phase power transmission applications, autotransformers have the limitations of not suppressing harmonic currents and as acting as another source of ground fault currents. A large three-phase autotransformer may have a "buried" delta winding, not connected to the outside of the tank, to absorb some harmonic currents. WebIf it went the other way, we'd be violating the law of conservation of energy. How the currents split between the halves of the autotransformer will then be determined by the windings ratio of the autotransformer, and the impedance of the load. Here's another direction to approach it. For an ideal (auto)transformer, P i n = P o u t.
