Web3. Arc quenching is much faster during operation of air blast circuit breaker. 4. The duration of arc is same for all values of small as well as high currents interruptions. 5. As the duration of arc is smaller, so lesser amount of heat realized from arc to current carrying contacts hence the service life of the contacts becomes longer. 6. WebJan 12, 2024 · Splitting of arc:- The resistance of the arc can be increased by splitting the arc into a number of smaller arcs in the series. Each one of these arcs experiences the … WebFeb 24, 2012 · What is an Arc?
