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.
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.
According to the National Fire Protection Association (NFPA®), an arc flash occurs “when an electric current passes through air between ungrounded conductors or between ungrounded conductors and grounded conductors.” Temperatures can reach 35,000 °F— three times hotter than the temperature of the sun.
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.
