Abstract :
The arc-circuit interaction plays an important role in the current interrupting process of high-voltage circuit breakers. For the development of circuit breakers, testing in the High Power Laboratory is necessary. For UHV circuit breakers new test circuits have to be developed. The design and development of new synthetic circuits relies on computer simulations only. A correct representation of the current zero behavior of the circuit breaker by means of an arc model is absolutely necessary. In this paper, arc modelling and the development of new test circuits are discussed and measurements of arc voltage and arc current are presented for two 72 kV SF6 power circuit breakers
