THE CHARGE SIMULATION METHOD FOR CALCULATION OF THREEDIMENSIONAL ELECTRIC FIELD BETWEEN PHASE WINDINGS OF A TRANSFORMER |
| |
| Abstract: | The three-dimensional electric field between phase windings of a high voltage ransformer has been calculated by using charge simulation method in this paper. tPoint charge is adopted as simulation charge. When the effects of oil-tank are considered, the image charges and voltage formulas are obtained. Since the effects of findite charges are only considered, there will be some errors in the calculation. In order to improve the precision and not to increase number of charges, the better results have been obtained by using optimized charge simulation method. From the calculted results, the value and position of maximal electric field are investigated. |
