Technical FAQs 4

What arc flash mitigation solutions are available?

Improve safety with our extensive portfolio of arc flash mitigation solutions including arc quenching and arc-resistant switchgear, Power Xpert XGIS switchgear, Power Xpert Dashboard, Power Defense molded case circuit breaker, Insulgard, arc flash relays and more.

Are arc flash and arc-flash studies a safety concern?

Arc-flash and arc-flash studies are also clarified. This White Paper also highlights a safety concern when HV/MV switchgear fails catastrophically, particularly oil-filled switchgear assembly. Within IEC Standards, HV switchgear are used on systems above 1 kV up to 52 kV. In North America MV is any voltage between 600 V and 69 kV.

What is arc flash protection in a substation?

The main purpose of arc flash protection in a substation is to protect both personnel and equipment from the consequences of an arc fault. Arc flash faults are the most devastating types of faults known in power distribution systems.

What are arc flash faults?

Arc flash faults are the most devastating types of faults known in power distribution systems. They can cause life-threatening injuries as well as severe equipment damage, leading to time-consuming repairs and extended power outages. The reliability of the AQ 100 series is based on our unbeatable experience in the field of arc protection.
