Abstract :
The need for ultra-rapid fault interruption is identified on the basis of improvements to generator stability and the power transmission capability of the BPA 500 kV system. The development of a modified 500 kV air blast circuit breaker and a special fault sensor, which in combination should reduce total fault duration to essentially one cycle, is then described.
