Abstract

This article describes a test setup and the results of comparing the partial discharge inception voltage of synthetic ester and gas-to-liquid insulation liquids under lightning impulse voltage of positive polarity. The design of the test samples is chosen to simulate a common insulation arrangement of power transformers: a paper-insulated U-shaped copper winding rod vis-`a-vis a copper plane in insulation liquid with a gap between
them. Partial discharges are detected via the occurrence of streamers and optical measurement thereof using fluorescent fibre optics, a photomultiplier tube and, an oscilloscope. The results are evaluated by field strength using conversion factors obtained by a finite element method simulation.
