| Popis: | Ferroresonance phenomena lead to damage to electromagnetic measuring voltage transformers and nearby equipment. Damping devices and antiresonance transformers, which are used for preventing the occurrence of ferroresonance phenomena, are effective in a certain area of influencing factors. The article presents methods for studying the possibility of occurrence of ferroresonance phenomena in the operation of 6-220 kV voltage transformers based on physical and mathematical modeling. The results of the tests according to the developed method are the area of the existence of a dangerous ferroresonance for the voltage transformer under test or the confirmation of its antiresonance properties in a certain range of influencing factors under study. The article also describes an experimental setup based on RTDS for conducting experimental studies. The developed methods were tested in the studies of one of the types of antiresonance transformers. |
