Breaker Arc Model
Updated August 26, 2019
This breaker arc model is based on Mayr and Cassie Equation. It shows the variation of breaker arc resistance during current interruption.
Three factors have impact on the arc resistance:
1. the injected power by the system.
2. the cooling power.
3. the arc time constant
