Abstract

The existing techniques for the detection and location of incipient faults (e.g. electrical trees) in extruded shielded power cables are reviewed. Only the techniques developed for field applications are included. The advantages and disadvantages of each technique are evaluated from the point of view of a power engineer. The desired features of an ideal incipient fault detection and location system are identified. Guided by these features, directions for future research in this area are suggested. The authors discuss partial discharge measurement and time-domain reflectometry
