Abstract

The characteristic of streaming electrification and static charge diminution in Cu, Fe and Sus pipes were investigated. The Cu and Fe pipes are charged positively, whereas the Sus pipes are charged negatively. Electrification rate in Cu and Fe pipes increases with increasing a pipe length for no-charged insulating oil. The electrification rate in Cu and Fe pipes abruptly increase with increasing the temperature and flow rate of insulating oil but decrease in Sus pipes. The current flows as a direction of insulating oil in all pipes.
