| Popis: | The short-circuit test is an important topic on the study of transformer features. With the shunt capacitor paralleled to the tested transformer, the test current can be reduced by the resonant of the capacitor and the inductance of transformer winding. Furthermore, using the high frequency power supply, the capacitor can be reduced in the resonant point because the high frequency values. In this work, the simulation model of short-circuit test of transformer with different frequency power supply is designed. Under variable frequency power supply, which are 50Hz,100Hz and 150Hz, the shunt capacitors value is given. From the simulation results, the application of the shunt capacitor takes a role in the short-circuit test of transformer. This has a significance role in transformer test research and engineering application field. |
