A Study on the Streaming Electrifacation in Forced Oil Cooled Transformer

When oil flows and rubs against various materials in transformer, electrostatic charges are separated at the interface of the oil and the solid material. Using simplified model transformer, authors investigated the basic characteristics of the streaming electrifica-tion which is caused by forced oil circulation. As the result of the study, it was concluded that the electrostatic charge distribution on test pipe of the transformer showed larger leakage current at the inlet and the outlet.
