Abstract
A system includes: a sensor configured to detect electrical signals of a cable section for transmitting electrical energy; a processor; a data memory; and a signal interface. The data memory stores a set of curves with an associated distance to the sensor and representing a pulse response of an electrical pulse predetermined by a cable model as a result of a modeled partial discharge at the associate distance. The sensor detects a discharge signal caused by an actual partial discharge on the cable section, and transmits a measurement signal to the processor. Based on the first measurement signal, the processor determines which among the curves in the set correlates best with the first discharge signal, as the first discharge curve. The processor determines a sensor distance between the actual partial discharge and the sensor based on the distance associated with the discharge curve. The signal interface transmits the sensor distance.
