Class: OpenCircuitTest

Open-circuit test results verify winding turn ratios and phase shifts. They include induced voltage and phase shift measurements on open-circuit windings, with voltage applied to the energised end. For three-phase windings, the excitation can be a positive sequence (the default) or a zero sequence.
