Abstract

The paper presents the new power processor and the first results of its application. Power processor is an electronic circuit which allows to separate the measured power signal (obtained from the multiplier circuit) to the components: P + and P- labeled in the literature as the input power Pv and the return power Pr, which is itself harmful, is heating back wires and supply transformers. It is produced by shifting the phase between the current and voltage and it is negative. Such natural division based on physical fenomena of energy direction and will be usefull in correct billing and dynamic power compensation. Theory is not based on standard power triangle and its difficult correction for dissortions.
