  journal={IEEE Transactions on Power Delivery},
This investigation examines and compares the loading characteristics and power factor values of V-V, Scott, and Le Blanc-connected transformers by a novel approach. Four definitions of power factor are compared-three considering harmonics and unbalances and one based only on fundamental components. A proper power factor value is needed to truly reflect the loading characteristics of these specially connected transformers, considering the influences of harmonics and unbalances. The computation… CONTINUE READING
