PARTIAL DISCHARGE DETECTION DEVICE CAPABLE OF DETERMINING THE EXTERNAL OR INTERNAL ORIGIN OF A PARTIAL DISCHARGE, AND ASSOCIATED METHOD

摘要

The invention relates to a device for detecting a partial discharge in an electrical device under voltage, the device comprising detection means (Pc) mounted on the electrical device under voltage, in order to detect at least one partial discharge that occurs, characterized in that it comprises additional means (D1, D2, S)capable of determining whether the partial discharge that occurs is inside or outside the device under voltage. Application to the factory testing of power transformers.
