Abstract :
The author presents a novel measurement system for testing electrification of transformer oil when moving a solid phase in a liquid-phase environment. The system is based on hydrodynamic phenomena occurring for a rotating disc in liquid. It is concluded that the spinning disc system is useful for examining the electrification of transformer oil. The results obtained, particularly those concerning the effect of oil aging electrification, agree with the results obtained by means of A. Klinkenberg´s (1958) system
