A self-calibrating partial discharge WSN for condition monitoring in the future smart grid

A self-calibrating wireless sensor network (WSN) of radiometers designed to detect PD radiation is proposed as a low-cost approach to real-time condition monitoring, asset management and operational optimization in the future smart grid. The principles of the proposed PD WSN are described in detail. Some early progress in the development of subsystems for a proof-of-principle prototype is also presented.
