simulation - Opis:
- Ferroresonance is a phenomenon usually initiated by transients in power networks resulting from e.g. switching operations or ground faults. Non linear behavior of the core of an inductive voltage transformer results in magnetic saturation. long-lasting ferroresonant state is dangerous to the equipment due to prolonged overvoltage and large overcurrents in HV windings.in the present article numerical simulations of the ferroresonance phenomenon in a HV inductive Vare presented. the ferroresonant oscillations analyzed result from interaction between the voltage transformer and a grading capacitance of a circuit breaker.
