Abstract
For an electrical system a sensor and associated circuits are provided for on-line monitoring of the state of the high-voltage insulation in the electrical system. In this arrangement, both the power frequency signal and of the radio frequency signals associated with partial discharge activity may be monitored and transmitted from the sensor to remote monitoring instrumentation. The sensor is disposed in a stand-off insulator which also may act to support the high voltage conductor system.
