PDF version includes complete article with source references. Suitable for printing and offline reading.
Switchgear designed and tested to mechanically withstand the electric arc. Protection is afforded by the containment of the arc within the switchgear and the means to direct the arc gases and debris to a safe area. Passive solutions also include advanced switchgear design features to reduce the probability of an arc flash occurring.
ABB's arc flash mitigation solutions keep your business running, improving uptime by limiting the energy of arc faults, therefore limiting the damage they cause to switchgear and assets and the repair time required. Maximum peace of mind.
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.
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.
