Abstract

SINCE LARGE POWER TRANSFORMER BELONG TO THE MOST EXPENSIVE AND STRATEGICALLY IMPORTANT COMPONENTS OF ANY POWER GENERATION AND TRANSMISSION SYSTEM, THEIR RELIABITY IS OF CRUCIAL IMPORTANT FOR THE ENERGY SYSTEM OPERATION. MOST SERIOUS FAILURE OF A LARGE POWER TRANSFORMER IS DUE TO THE INSULATION BREAKDOWN. PARTIAL DISCHARGE (PD) THAT DAMAGE INSULATION BY GRADUAL EROSION IS A MAJOR SOURCE OF INSULATION FAILURE. TECHNIQUES FOR LOCATING A PD SOURCE ARE OF MAJOR IMPORTANCE IN BOTH THE MAINTENANCE AND REPAIR OF A TRANSFORMER. THE LOCATING METHOD OF PD CAN BE MAINLY CATEGORIZED INTO TECHNIQUES BASED ON ACOUSTIC SIGNALS OR ELECTRICAL SIGNALS. THE ADVANTAGE OF ACOUSTIC LOCATING METHOD IS ITS SIMPLE ALGORITHM AND NOISE-PROOF FEATURE, BUT ITS SENSITIVITY IS BAD AND THE CONSTRUCTION OF TRANSFORMER IS TOO COMPLEX TO FIND THE SPEED OF ULTRASONIC WAVE CAUSED BY PD. THE ELECTRICAL METHOD HAS A BETTER SENSITIVITY BECAUSE IT DEPENDS ON PULSE CURRENT SIGNALS MEASURED AT TRANSFORMER TERMINAL.AT THE MOST COMMON STATUS IN THE FIELD, THE DISCHARGE BETWEEN THE WINDING OF THE TRANSFORMER AND THE GROUND WAS ANALYZED. ANALYSIS OF PD IN THE COIL TO COIL CAPACITANCE IS DIFFICULT SO THIS OBJECT WAS NOT CONSIDERED COMPLETELY. IN THIS PAPER PARTIAL DISCHARGE IN THE INSULATION BETWEEN COIL TO COIL IS CONSIDERED WITH EMTP SIMULATION TOOLS. THEN THE CURRENT OF NEUTRAL POINT OF WINDING IS MEASURED WHEN PD MODEL IS LOCATED AT DIFFERENT POSITIONS IN THE WINDING. THIS CURRENT WILL BE ANALYZED WITH THE DB2 WAVELET. WITH COMPARE DETAIL LEVEL (1) PD CAN BE LOCALIZED.
