Abstract

In this paper, we developed an intelligent spacer built into the internal type UHF PD sensors. 3-dimensional electro-magnetic simulations were performed to analyze electric-field distribution of the single-phase GIS and three-phase GIS. After considering the spacer´s specifications, sensor structures were designed and analyzed using the 3D EM simulator. As a result of the simulation the internal type UHF PD sensors were built in. Performance of the sensor built into the real-scale GIS spacer was measured in terms of return loss and detected max voltage. We identified a characteristic of the intelligent spacer by using 5pC partial discharge cell.
