Power definitions, power quality, measurement, line losses, neutral wire.
It is well known that the power factor is the relation between active power and apparent power. Moreover, the square of the power factor represents the relationship between the minimum power loss and the present power loss. This paper deal with the decomposition of the latter ratio into three factors; the first related to the current imbalance, the second to the current distortion and third to the reactive power consumption. Once the contribution of each factor is known, it is posible to determine which disturbance produces the greatest losses. This concept is applied to a three phase-four wire system, with and without neutral resistance.
