Abstract :
The electric field in flowing charged oil in an oil/pressboard (PB) composite insulation system was directly measured by an electro-optic Kerr effect. We discussed the charging mechanism and proposed the charge behavior model based on the measurement results. We compared the results of measurements and calculations and confirmed the validity of charge behavior model.
