Analysis of Networks with Complex Autotransformers III-Invariant Reduction for Purposes of Loss Formulas

An expression for an accurate loss model has been derived for general systems containing off-nominal or complex off-nominal autotransformers and impedances to ground. This was achieved by carrying the open-path-closed-path relations derived in earlier papers in this series through the necessary reference frames. The loss model derived in this manner can be implemented in modern dispatching computers.
