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.

How to evaluate arc rated switchgear in Canada?

Canada use CSA C22.2 No. 0.22-11 “Evaluation methods for arc resistance rating of enclosed electrical equipment” to evaluate internal arc rated switchgear. Internal arc type testing is very important to reduce the risk of exploding switchgear.

Can a relay and breaker be used to clear an arc flash?

Relay and breaker settings can often be optimized to trip quickly to clear an arc flash event but also maintain coordination. When coordination cannot be maintained to achieve desired arc flash results, a maintenance switch can be added.
