Abstract

his paper describes a vehicle mounted radiometric system consisting of an array of four antennas connected to broadband, high-speed recording hardware capable of locating the source of partial discharges (PD). The significant advantages of the system lie in its ease of application, not requiring any electrical plant interface, and its ability to monitor emissions from several items of plant simultaneously. The system has been widely used at transmission level.
