摘要
An on-line monitoring system of partial discharge and interlayer short circuit of a high voltage circulator is provided to previously monitor an error of the high voltage circulator by monitoring an interlayer short circuit signal of a rotator and a partial discharge signal of a stator in an operating state of the high voltage circulator. An interlayer short circuit sensor(121) is installed at a stator(120) in order to sense interlayer short circuit of a coil of a rotator(110). A partial discharge sensor(122) senses partial discharge of a coil of the stator. A first and second data collection units(210,220) convert output signals of the interlayer short circuit sensor and the partial discharge sensor into monitoring and analysis data. A server(300) collects a partial discharge signal and an interlayer short circuit signal from the first and second data collection units through a communication line(250) and displays and transmits the collected signals.
