High-voltage circuit breakers, present in the power grid, ensure in safety the electricity distribution. When an error is detected, or for a maintenance operation, the opening of the electrical contacts within the circuit breaker causes the appearance of an electric arc at its terminals. Protection and cut-off will only be effective if the electrical arc cut off. Many parameters, geometric and physical, are involved in the breaking capacity of a circuit breaker. The aim of this work is to analyze the impact of plasma on the various materials making up the circuit breaker. A purely theoretical approach is tackled through the use of the commercial software ANSYS Fluent. This work is carried out in collaboration with Siemens, which provides th...
