Primary testing is the ultimate way to ensure the functionality of the breaker because it's reproducing exactly what's happening when the breaker is in service. That said, it's often time consuming, expensive, and for large breakers can get logistically difficult. Secondary injection is much faster, easier, and cheaper. WebInability to conduct primary injection testing in the proper manner could result in inappropriate test results, while ultimately damaging the integrity of the circuit breaker long term. The circuit breaker is automatically restored to normal mode in 75 minutes, if the test functions are not manually stopped prior to that. data transfer pixel
