Abstract :
A mathematical method for evaluating the probability of extreme magnitudes of switching surge overvoltages is proposed which includes correlation among the three phase circuit breaker pole closing times. The model utilizes published data for trivariate and bivariate normal probability functions. Examples are presented which illustrate critical aspects of the calculations, and suggestions are made regarding specific applications.
