SF6 Breakers tester

SF6 Breakers tester

The purpose of "Doble testing", or power factor testing, SF6 (sulfur hexafluoride) circuit breakers is to detect the presence of contamination and/or deterioration of the breaker's insulating system. This process will allow corrective actions to be taken to ensure the integrity of the breaker.
