Abstract

PURPOSE: In a vessel 1 with machine proper 2 to 4 and insulating liquid 5 which is circulated from an oil pipe 6 to a cooler 7 by an oil pump P, the liquid charges electricity to cause accidents of dielectric breakdown and so forth. The charges increase to their maximum in a little while after starting the pump operation and then decreases to a constant value. At that time of the maximum, valves V1 and V2 are switched to flow liquid to a side pipe 10, the amount of charge flowing into the vessel 1 can be decreased,. Further, charges can be decreased by providing the sending side 6B of the oil pipe with a thermostat and/or charge neutralizer.
