Abstract

The paper considers and researches the voltage breakdown process of circuit-breaker epoxy bushing and presented the mathematical model of the process of their damage. It was discovered that electrical breakdown channels in circuit-breaker epoxy bushing are the outcome of both, the constructive coordination of insulation fault and cumulative effect that is received from stray wave lightning impulse string.
