High-frequency and low-frequency components of the capacitive switching transients in power mains

Abstract

At the connection of a load (typ. a capacitor) across the power-mains live wires a transient disturbance is excited, containing both a low-frequency waveshape (lumpedparameter analysis) and a high-frequency waveshape (wavepropagation analysis). The role of dispersion due to a nonideal dielectric is pointed out, in relation to the high-frequency component.
