Abstract (en)

[origin: WO2022012720A1] The invention relates to a device for determining a charge strength of a partial discharge, comprising a measurement device and an evaluation device (4). The measurement device is configured to detect a measurement signal which indicates a pulse curve of a measurement variable, said pulse curve being caused by a partial discharge in a conductor (1), and to generate measurement data indicating the measurement signal. The evaluation device (4) is configured to receive the measurement data from the measurement device, to determine a pulse width of the pulse curve based on the measurement data, and to determine a charge strength of the partial discharge based on the pulse width of the pulse curve. The invention also relates to a method for determining a charge strength of a partial discharge.
