Parameters Identification of Partial Discharge Circuit Sensors Based on Vector Fitting
Yun Liu · Electric Power Science and Engineering · 2003
The characteristics of partial discharge can be detected by the wide band partial discharge measurement of the current sensor. The transfer characteristics of the sensor are studied by vector fitting. The frequency response curve of the sensor has been tested. Rational function is used to fit the frequency response based on tested data. The transfer function of the sensor is obtained. It can remove the aberration of current sensor and recover the original partial discharge received by the sensor.
