“…Generally speaking, the breakdown voltage is much smaller in a contaminated transformer liquid with smaller viscosity. It was found in [7] that the movement of conductive particles in electric field is restricted by the viscous resistance of surrounding liquid. Both the accelerations and the velocities of conductive particles in a viscous liquid are much smaller.…”

This paper investigated the motion of a metallic cylinder particle of mm size under uniform AC field in three transformer liquids, including a mineral oil, a synthetic ester and a natural ester. The clean transformer liquids were also artificially contaminated by copper particles of μm size, and the relationship between the AC breakdown strengths and the amount of copper particles was determined. It is found that the breakdown voltages of esters are influenced by metallic particles to a less degree than mineral oil. The slower motion of metallic particles in esters of higher viscosities than mineral oil reduce the chance of breakdown, and this might account for the better performance of esters under AC stresses with the existence of metallic particles.
