A: 5 steps towards resuming operation after an arc fault:
A: Counter question: What is at stake for you if production is interrupted for weeks on end? Because that is exactly what can happen if no redundant power supply is available. By implementing an active arc fault protection system, production downtime due to arc faults can be reduced to a minimum.
Unfortunately, serious arc fault incidents are frequently caused by operating errors. Here, effective protection is available through technical means. In practice, a professional risk assessment also often leads to the introduction of arc fault protection measures.Just ask yourself this question: Would you be willing to do without the airbags or maybe the ABS in your car?
A: There is a risk, e.g. for people who are near the switchgear assembly during an arc fault. Even if the assembly is closed, they can suffer injury due to toxic gases.
Remember that the protection against thermal effects and overpressure is ineffective when the switchgear assembly is open for maintenance and operation.
