Abstract: A method of detecting a partial discharge in an electrical asset includes sensing of a discharge current in the electrical asset using a transducer and responsively providing a transducer output; processing the transducer output by comparing the transducer output to a baseline; calculating an accumulated amount by which the transducer output exceeds the baseline; decreasing the accumulated amount with time; detecting partial discharge in the electrical asset based upon the accumulated amount; and providing an output related to detected partial discharge. A partial discharge detection system for detecting a partial discharge in an electrical asset includes a transducer configured to receive a signal from the electrical asset generated due to an occurrence of partial discharging in the electrical asset and responsively providing a transducer output. Processing circuitry compares the transducer output to a baseline, calculates an accumulated amount by which the transducer output exceeds the baseline, decreases the accumulated amount with time, and detects partial discharge in the electrical asset based upon the accumulated amount. Output circuitry provides an output related to detected partial discharge.

Abstract: A sensor module for monitoring an asset in an electrical power generation or distribution system includes a module body, a sensor, a sensor near field coupling structure, and an interrogation near field coupling structure. The sensor is supported by the module body, arranged to sense a parameter of the asset and configured to generate a sensor output relating to the parameter. The sensor near field coupling structure is connected to the sensor and supported on a first side of a module body. The interrogation near field coupling structure is supported on a second side of the module body. The sensor output is transmitted from the sensor near field coupling structure to the interrogation near field coupling structure. The sensor module is configured to provide electrical isolation between the asset and a monitoring circuit configured to receive the sensor output through the interrogation near field coupling structure.
