Abstract

Voltages and currents in the frequency range from 2 to 150 kHz (supraharmonics) are generally assumed to have a short distance of propagation. They are expected to be damped within the direct neighborhood and have their highest magnitude directly at their source. This paper presents measurements of the supraharmonic propagation in a typical residential and a typical commercial low voltage network. While an effective damping is observed in upstream direction, in downstream direction significant resonance amplification at frequencies between 2 and 20 kHz was found. For one network, the resonance is validated by simulation. The results show a good match with the measured values.
