A Study on the Streaming Electrification of the Energized Couette Charger

A Couette Charger was used to simulate streaming electrification process in transformer. This paper describes the electrification characteristics of the energized and unenergized Couette Charger. By applying low frequency and high voltage across the cylinder of the Couette Charger, the measured short circuit current$i_{sc}$) is compared with the measured values of unenergized Couette Charger. As a result, short circuit current was increased with voltage.
