Pilot implementation of the on-line partial discharge monitoring system for heads of the high voltage cable lines

Abstract

The article presents the assumptions, characteristics and description of the implementation of a pilot systemfor on-line monitoring of partial discharges in heads of the high-voltage cable lines. The main purpose ofthe implementation was to increase the reliability of cable line heads by equipping them with a system ofcontinuous assessment of technical condition with direct transmission of measurement data and alarms tothe SCADA system. In order to achieve the assumed goal, unconventional methods for measuring partialdischarges were used, the application of which does not require disconnecting the line from the voltage.The implementation was carried out on an active 110 kV high voltage cable line in the area of activity ofone of the Distribution System Operators.
