This month’s Featured Technical Paper is from the Proceedings of the 2019 International Conference of Doble Clients. The paper is titled: Study of Diagnosis of Aged Resin Type Bushing by Electro-Magnetic Wave Detector.
TEPCO Power Grid has decided to replace bushings of outdated designs, which have specific deterioration issues, such as those caused by the resin design. Many of the bushings are in use so it is necessary to carry out the replacements in order of priority based on the level of bushing deterioration. TEPCO PG has developed diagnosis methods and established criteria to detect deterioration at an early stage by PD detection with acoustical emission (AE) sensors and Electro-magnetic wave detectors. This paper will report the progress of our research at TEPCO PG regarding bushing failure occurrence and the deterioration diagnosis methods.
