Abstract :
The purpose of this paper is both the experimental verification of the theoretical model of electric field in arc presence and developing a new circuit breaker design approach. The experimental idea was based on numerical calculation. It consists of measurement of back strike probability for two dummy embodiments. The calculation has shown that the back strike must take place in the first embodiment, but the back strike probability is zero in the second embodiment. The experimental measurements confirm the numerical calculation results fully.
