Abstract :
An on load pressure rise in a puffer chamber of puffer type gas circuit breakers (GCB) is higher than a no-load pressure rise. A method of calculation of the on-load pressure rise has been developed. The calculation results show good agreement with the on-load pressure rises measured with an experimental puffer type GCB.
