Abstract

Several undesired high-frequency phenomena take place in industrial drive systems supplied by PWM frequency converters. Along with the well known transient overvoltages at the motor terminals due to the inverter pulses propagation and reflection, transient currents flow between the phase conductors and from them to the ground, resulting in further problems. In this paper, the influence of the cabling characteristics on the intensity of these phenomena is adressed by means of a theoretical-computational investigation. The obtained results provide useful and practical information concerning industrial cable installation issues.
