Abstract: In this work, a new method for calculating the parameters of electric arc model for SF6 power circuit breaker is proposed. The methodology consists in the optimization of a theoretical function with respect to a group of model parameters in order to achieve a better approximation to a set of experimental data. The theoretical function is an asymptotic solution of the equation for the ...

With the development of flexible low frequency transmission technology following improvement offshore wind power transmission, it is great significance to investigate operation adaptability main equipment especially under conditions. A comparative study was performed in present work discuss dynamic performance a 252 kV/50 kA puffer-type circuit breaker influenced by system operational frequency...

The general trend in electrical appliances is to go for electrical equivalents of mechanical or electromechanical gadgets. One of the long standing electronic component is the circuit breaker, a protective device that trips the ac supply once the current through the system goes beyond the rated value. In this paper an all electronic circuit breaker using bidirectional switch is demonstrated. Th...
