Abstract

PURPOSE: To detect a generating condition of static electricity caused by a drift charge in the transformer, by such means that with a sampling of insulating fluid processed from transformers, a level of its drift charge, specific resistance of the fluid and/on tan δ be measured, obtaining a hazardous signal from a specific relation between the both.
CONSTITUTION: At the time of detecting a generating condition of static electricity, with an oil pick-up valve 6 made open, a sampling of the fluid will be processed from outlet part of an oil pump 5. The fluid, made sampling, flows into a container 10 through a valve 8, circulating as a circulating pump 12 operates in a circulation route including a measuring unit 9. During this circulation, a measurement is made for a level Is of drift charge by the measuring unit 9, and specific resistance ψ of the fluid or dielectric loss factor tan δ by a sensor 11, with a decision of static electricity generating condition in the transformer operated by a signal processing for if locating in a critical range, and at a critical time, a signal for that meaning will be generated.
