<p>The present invention relates to a diagnostic method of insulating oil for a transformer, which analyzes the insulating oil while comprehensively considering representative deterioration factors that degrade the performance of the insulating oil and allows the state and replacement time of the insulating oil to be determined on the basis of the result of analysis of the insulating oil; and to a diagnostic apparatus of insulating oil for a transformer. The diagnostic method of insulating oil for a transformer performs the steps of agitating the insulating oil extracted to diagnose the insulating oil by an agitator for a fixed time; measuring representative deterioration factors that degrade the performance of the insulating oil by a measuring instrument with respect to the insulating oil which has been agitated; applying the measured values of the representative deterioration factors to a discriminant interaction equation to diagnose the insulating oil in an insulating oil determination unit, thereby calculating a correlation value; and analyzing the correlation value calculated in the insulating oil determination unit to determine the state of the insulating oil. Accordingly, the present invention helps the state and replacement time of the insulating oil to accurately be determined, and allows the state of the insulating oil for the transformer to quickly and accurately be determined by offering the discriminant interaction equation to determine the state of the insulating oil.</p> |
