Abstract
A partial discharge detecting device includes an electric field sensor including: a first electrode configured to detect by capacitive coupling a partial discharge signal generated by an electrical object and to provide a corresponding first electrical signal, and a second electrode isolated from the first electrode and structured to detect an environmental noise and to provide a corresponding second electrical signal. The detecting device further includes a transmission line structured to propagate an output signal obtained from the electric field sensor toward an external analysis apparatus and an electronic module connected to the first and second electrodes and structured to process the first and second electrical signals and to provide the output signal to the transmission line. The electronic module is structured to decouple the electric field sensor from the transmission line and avoid resonance of the electric field sensor with the transmission line.
