An arc-flash occurs when the air surrounding a conductor becomes ionized, allowing the air itself to become an electrical conductor. The resulting fault current creates a dangerous and potentially fatal release of thermal energy. High-speed arc-flash detection can significantly reduce the hazardous energy released in an arc-flash event. In this webinar, you will learn about the benefits of having fast and reliable arc-flash protection, as well as the pros and cons of different arc-flash detection methodologies. In addition, the webinar will show actual arc-flash incidents that were protected by the SEL-751A Feeder Protection Relay.
