METHOD FOR LOCATING PARTIAL DISCHARGES IN AN ELECTRICAL EQUIPMENT, SYSTEM FOR LOCATING PARTIAL DISCHARGES, AND COUPLING UNIT

摘要

The invention relates to a method for locating a partial discharge in high voltage electrical equipment (10) insulated by a dielectric fluid comprising at least a first and a second UHF sensor (11, 12). The method comprises the following steps: E1 recovering a first and a second signal, separating each of the first and second signals into at least two representative signals, combining the representative signals, calculating an interference function a from representative signals in the frequency domain, and determination of the location of the partial discharge from the calculated interference function. The invention further relates to a partial discharge location system and a coupling housing occupying such a system.
