Arc flash resistant equipment may be described as the equipment made to withstand the impact of internal arcing fault by meeting the testing requirements of IEEE Guide C37.20.7-2007. In the 1970s, an interest started in Europe in assessing electrical equipment under internal arcing, which lead to IEC standard. This research spread to North America and was used as a foundation for EEMAC G14-1 procedure. The development of IEEE standard heavily relies on Annex AA of IEC standard and adopts many of the refinements originated in EEMAC G14-1 procedure. IEC 62271 - 200 defines the requirements for factory assembled metal - enclosed switchgear and control gear for alternating currents at rated voltage above 1 kV and up to and including 52 kV. It includes indoor and outdoor assemblies and frequencies up to and including 60 Hz. This course is suitable for electrical engineers with a desire to find out more about arc flash resistant equipment. Presented details discuss IEEE and IEC equipment accessibility types, arc resistant ratings and testing procedures according to IEEE standards. Upon successful completion engineers will have more information about usage of arc flash resistant equipment and its proper application. Learning Objectives Specific Knowledge or Skill Obtained
