Abstract

Due to significant influences of rapidly changing load crosstalk on characteristic of zero sequence voltage in resonant earthed networks there is an increasing demand for reliable method of proper and reliable Petersen-Coil (Arc Suppression Coil, ASC) tuning. Also increasing cabling of the distribution networks causes ever higher demands on ASC tuning systems.This paper will present new method of ASC tuning based on the injection of truly multifrequency current signal into zero sequence system through network’s neutral point. Indirect measuring of voltage response in zero sequence system (Neutral Voltage Displacement) enables then to evaluate the tuning status of the ASC very precisely.
