Method and system for leakage diagnosis of insulating oil

Abstract

A method and system for leakage diagnosis of an insulating oil, which can be used for early warning of oil leakage anomalies of a transformer. The transformer includes an oil storage tank and an insulating oil located in the oil storage tank. The system includes a detecting device and a diagnosing device. The detecting device includes a sensing module and a processing module. The sensing module is disposed on the oil storage tank to acquire status information of the insulating oil within at least one unit time interval. The processing module is connected to the sensing module to establish a conversion function relationship between the oil temperature and oil level of the insulating oil by using the status information. The diagnosing device is connected to processing module, and is configured to perform oil leakage early warning of the insulating oil according to the conversion function relationship during operation of the transformer.
