Power electronics and electrical insulation systems ߝ Part 1: Phenomenology overview

Abstract

It is well known that the wide use of power electronic converters (PEC) is one of the main causes of current and voltage distortion in the electrical networks. These converters generate harmonic components propagating toward the supply network side and nonsinusoidal voltage at the load side. Distorted waveforms generated by power electronics can dramatically reduce the reliability of insulation systems. Such systems should be designed bearing this important factor in mind.
