Detector of covered conductor faults

Abstract

In the Czech Republic are distribution lines with bare conductors replaced by distribution lines with covered conductor. The PAS system with covered conductors has many advantages and disadvantages that are described below. This article describes issue of fault detection for distribution lines with covered conductors, dependence of partial discharges on fault and finally the design plus realization fault detection of covered conductors. This is a prototype which will be tested and then optimized. The system will be used for different voltage levels and different types of outdoor distribution lines.
