Abstract

A reliable assessment of the current condition and preferably the remaining lifetime of an electrical equipment of high voltage cable systems is playing an important part in achieving a sustainable development and upgrading of the power grid. Partial Discharge (PD) measurements and diagnosis are considered as a valid tool for evaluating the condition especially of cable systems. The recently discussed optical measurement of PD in high voltage cable accessories using integrated fiber optical sensors has significant advantages over the electrical PD measurement according to IEC 60270 since it is completely insensitive to any electromagnetic interference. Non-electrical methods are an interesting alternative, especially for on-site testing. This article describes the on-going work on the integration of special fluorescent optical fibers made of silicone elastomer (E POF) into a test specimen with a tip-plate configuration and the optical detection of PD using these optical sensors. The used insulating material is a transparent silicone elastomer whose optical properties have also been investigated. Measurements are taken in a darkened cabin on a PD measuring circuit according to IEC 60270 using an optical converter (APD). Beforehand, the adaptation of the sensors and the APD was examined to confirm the functionality of the system.
