The paper investigates the measurement and propagation of voltage unbalance at a distribution transformer. The relations between unbalance factors in voltage and current with the direction of negative sequence fundamental frequency active power are investigated. The goal is to evaluate possible applications of the principles derived by a simulation study in the practical assessment of how much variation in voltage asymmetry is contributed at an interconnection due to loading and how much is due… CONTINUE READING
