IEEE Seminar: Arc-Flash Resistant Switchgear

IEEE Power and Energy Society Chapter Richland Section/WSUTC Student Chapter
Social at 5:30pm, talk at 6pm

Speakers: Mark Lopez and Jayamali Arambewela, Crown Technical Systems

Abstract: Equipment or insulation failure or short between conductors can give rise to arc flash that are fast and deadly and results in temperatures as high as 30,000F. The arc pressure wave or blast accompanying an arc can cause an explosion and propel hot gases and molten metal to the surrounding atmosphere.  Exposure to arc flash can result in severe burns, hearing loss, blindness and even death. Arch resistant switchgear is specifically designed to contain and limit the damage incurred from an internal arc fault within the faulty switchgear or in the compartment.  Therefore it provides the highest degree protection to personnel against the effects of an internal arcing fault.  In this talk we will discuss the following topics (1) Arch flash causes and physical effects, (2) what is an arc resistant switch gear, (3) Basic standard ANSI IEEE c37.20.7 ratings, (4) Arc type testing, analysis and review, (5) available designs and switch gear safety features.
