Designing Better Circuit Breakers Using ANSYS Fluent — ANSYS Maxwell Multiphysics Simulation

A circuit breaker must dissipate a large amount of energy in a short time to protect an electrical circuit from damage. Evaluating and testing circuit breaker designs to ensure performance is, however, extremely cost- and time-intensive. Traditional, destructive testing often fails to explain the cause of the failure. In these cases, simulation can help designers to study circuit breakers and evaluate design changes in significantly greater detail than physical testing allows.

In this on-demand webinar, we’ll present a multiphysics simulation-based approach for evaluating electric arc movement inside the circuit breaker. This approach combines ANSYS Fluent and ANSYS Maxwell and has been validated for industrial megawatt circuit breakers. It helps designers understand the causes of circuit breaker design failures. With better insights, designers can narrow down their design choices for physical testing and validation.
