METHOD OF PREDICTING PROBABILITY OF ABNORMALITY OCCURRENCE IN OIL-FILLED ELECTRICAL DEVICE |
摘要 |
The present invention is a method of predicting the probability of abnormality occurrence in an oil-filled electrical device, including the steps of: measuring a residual dibenzyl disulfide concentration in an insulating oil sampled from an oil-filled electrical device in operation; determining an estimated decrease of the residual dibenzyl disulfide concentration, relative to an initial dibenzyl disulfide concentration at the start of operation of the oil-filled electrical device; calculating the initial dibenzyl disulfide concentration from the residual dibenzyl disulfide concentration and the estimated decrease; and comparing the initial dibenzyl disulfide concentration with a specific management value.
