Evaluation of Variation Ranges of Phase Voltages and Ground Currents in Three-Phase Unearthed Networks With Diode Rectifiers

Power and Electrical Engineering 2016
Piotr Olszowiec

Operating parameters of electrical networks such as phase voltages, leakage and ground fault currents are decisive for safe operation of low-voltage unearthed networks with diode rectifiers. The knowledge of maximum possible values of network operating parameters is necessary for correct assessment of numerous hazards. So far no simple methods of determination of the highest levels of these parameters in AC/DC IT 3-phase networks have been available. The present paper reports a new approach to the evaluation of the variation ranges of the operating parameters of these systems using Mathcad.
