In the short circuit breaking test of circuit breakers in accordance with rated operation sequence
its arcing time shall cover such three intervals as the minimum
medium and maximum arcing times. For certain circuit breaker
the measures of prolonging arcing time shall be taken to perform the test at maximum and even medium arcing time. In this paper
the parameters of prolonging arc circuit of impulse current are calculated and the calculation formula of the prolonging arc circuit are given. Its operation conditions are analyzed and the method on how to overcome above problems are described. The wiring and possible structure form of the suggested prolonging arc branch are proposed.
