High Voltage Instrument Transformers Ferroresonance Events Occurring in the Investigation of the Circuit Breaker Switch Positions

摘要

The Transformers in the power system is one of the most widely used elements. Transformers working in the linear region with a yield of electromagnetic energy provides a high rate conversion. However, with the onset of saturation of the transformer ferromagnetic core begins to fall due to the efficiency of energy conversion losses start to increase. Any power system elements constituting a sudden ferrorezonans are enough potential for the realization of the event. These elements of the transformer inductance and non-linear loads can be summarized in the resistance and capacitance. In this study, high-voltage transmitter to the controlled switched my order to make semiconductor power electronic switching elements connected with the resistance and capacitance cargoes including ferroresonance instantly switches opening and closing built resonance will occur in the electrical events, actual circuit conditions were investigated.
