Abstract
An algorithm for fast evaluation of negative phase sequence voltage caused by three phase-to-phase loads has been described. It is specially useful in the determination of an optimal power supply scheme where unbalance level at the PCC needs to be kept low. The algorithm can be extended to any calculations which involve the summation of three 120° phase displaced phasors or vectors
