Characterization of the electromagnetic environment with the installation of industrial rectifiers

A simple method of measuring harmonic flows and potential electromagnetic interference levels in power systems and communication circuits is proposed. Harmonic emission is correlated with existing plant susceptibility, leading to valuable information for rectifier design and filtering requirement identification. A theoretical model based on an actual Canadian utility proves that modelling at harmonic frequencies is very limited. This model also points out the need for field tests versus simulation for design purposes.
