Abstract
An apparatus and method for detecting a partial discharge produced at a discharge site in electrical equipment or accessories are provided. The apparatus includes two sensors having an operating range below 30 Megahertz, between 5 and 30 Megahertz, between 14 and 20 Megahertz, or centered at 18 Megahertz. The apparatus includes an acquisition module, a processor and an alarm module producing an alarm upon detection of a partial discharge in the electrical equipment or accessories. The method includes detecting magnetic fields with the sensors, generating and receiving two signals and producing a resulting signal by processing the two signals. The processor is configured to issue alarm instructions if the resulting signal exhibits a property representative of a detection of the partial discharge and otherwise remain in a standby state (ready for signal detection). The method includes generating an alarm after issuing the alarm instructions.
