摘要: The present paper deals with the influence of oil mixtures based on mineral morphology and final length Lf creeping discharges over solid/liquid interface. Two are considered: a mixture (A) consisting 20% by volume silicon oil, (B) synthetic ester. solid samples issued from bakelite, glass or polycarbonate. experiments achieved under impulse voltages using pointplane electrode arrangement. It is shown mat dielectric strength solid/mineral structures improved when replaced one these mixtures. shorter in B than oil; between A. results an increase flashover voltage insulator B. (U) increases quasilinearly whatever
