Abstract
The opening motion characteristic of circuit breaker equipped with hydraulic mechanism is analyzed. The mathematical model of the opening process is developed. The results show that such characteristic is greatly affected by the ambient temperature. Therefore the compensation for the change of such characteristic with temperature is put for-ward.
