Abstract

This paper persents the measurement method using a spinning cylinder system for stream-ing electrification of transformer oil. The spinning cylinder system has a simple mechan-ical construction, and requires less oil com-pared to the other methods. Alse, the effects of various admixtures on the static electri-fication and properties of tranformer oil can be easily investigated. Experiments showed that addition of the BTA reduced the streaming electrification and the polarity of static electrification wasconver-ted to negative at 50 ∼ 70[ppm] of BTA
