 note = {From viewpoints of low environment impact, Palm Fatty Acid Ester oil (PFAE) is potent insulating  liquid for power transformers because of its high biodegradation performance. Moreover, PFAE has  high permittivity, low viscosity, high thermal and chemical stability and high productivity.  These characteristics well satisfy the requirement of electric insulation performance in power transformers. In this paper, electric field distribution in a PFAE / pressboard insulation system was measured with a Kerr electro-optic technique at various oil flow conditions under dc voltages and the charge behavior was investigated systematically. We discussed the difference of the flow electrification characteristics between PFAE and mineral oil, and its mechanism was discussed based on the charge behavior in oils.},
