In a high-voltage installation, for example a tube gas line, several partial discharge measurement probes are provided that detect electromagnetic signals of partial discharges. The corresponding measurement data is supplied to an evaluation device that includes a neural network that is trained in such a way that it determines the location of occurrence of the partial discharge from the measurement data of two sensors.

Method for determining the location of a partial discharge

To perform a reliable and calibrated measurement of partial discharges, a first calibratable sensor and a second sensor are arranged in a metal enclosure. The first calibrated sensor picks up signal components in the HF (High Frequency) range, and the second non-calibrated sensor picks up signal components in the UHF (Ultra-High Frequency) range. An HF signal component picked up by the first sensor is transmitted to a partial discharge analyzer. The opening time of the gate device is determined by a UHF signal component picked up by the second sensor.
