Low-voltage switchgear and controlgear - Active arc-fault mitigation systems. Arc quenching devices not-eligible b) pile driving formulae –What is BS EN IEC 60947 9 1 Arc quenching devices about? BS EN IEC 60947 9 1 is the first part of an international standard that focuses on low voltage switchgear and control gear. BS EN IEC 60947 9 1 covers low voltage arc quenching devices hereinafter referred to as AQDs, which are intended to eliminate arc faults in low voltage assemblies, by creating a lower impedance current path, to cause the arcing current to transfer to the new current path.
