Abstract

Analysis of current and voltage 0-components in a three-phase four-wire circuit is made. It is shown how to select part of the circuit without the current and voltage 0-components which is equivalent to the original circuit in terms of instant power without the 0-component. For sinusoidal processes with asymmetric voltage, a computation algorithm for neutral current compensator LC elements conductivity is proposed. For symmetrical voltage, a 0-compensator susceptance calculation methodology based on load conductance is presented. Example calculations are analyzed.
