چکیده
leads and windings due t o eddy cu r ren t s induced in the conductors by t h e al ternat ing magnetic field. The leads and windings a r e connected in series, therefore, t he high-frequency resistance of t he transformer R t is An accurate, analyt ical method is proposed f o r calculating the lead and winding high-frequency resistance of complex transformer constructions. High-frequency resistance is derived from the result ing matrix system equations, common t o the leads and windings. The effect of eddy cu r ren t s in tht! leads is confirmed by theoret ical results. The high-frequency resistances of t h ree winding arrangements a r e compared, and from th i s resul ts , a winding geometry t h a t reduces winding high-frequency resistance is derived. R t = R L +Rw (1) where R I is t h e lead resistance and Rw is t he winding resistance. The goal of t h i s s tudy is t o provide methods t o calculate R i and Rw. winding

متن کاملClassification of transformer faults using frequency response analysis based on cross-correlation technique and support vector machine
One of the most important methods for transformers fault diagnosis (especially mechanical defects) is the frequency response analysis (FRA) method. The most important step in the FRA diagnostic process is to differentiate the faults and classify them in different classes. This paper uses the intelligent support vector machine (SVM) method to classify transformer faults. For this purpose, two gr...
