Abstract
The paper focuses on the modeling and simulation of the arc discharge phenomenon on circuit breaker of transmission line based on the energy balance model using the EMTP software. The Cassie and Schwarz arc discharge models are used to evaluate the parameters of the electric arc that occurs in the single-phase and three-phase short circuit phenomenon. The simulation results show the changes of the resistance, voltage and current values of the arc that appear between the two poles of the circuit breaker. The Cassie model combined with the Schwarz model has solved the problem of simulating the arc discharge phenomenon in the circuit breaker for the case of large current and the case of near-zero current.
