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.

Does switchgear have an internal arc type test?

When IEC 62271-200 was implemented in 2003, if switchgear was internal arc tested, the main MV compartments were tested, i.e. the switching, busbar and connection compartments. It is also a common misnomer that the internal arc type test is mandatory. The internal arc type test is an optional test within IEC 62271-200.

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 does Roxtec help switchgear pass internal arc type tests?

Roxtec produce a cable sealing product which helps switchgear pass internal arc type tests. Internal arc type tests are one of the most safety critical type tests for switchgear that impact the end user.
