The arc protection system can protect the operators from harm and reduce the property loss degree in case of arc fault in the switch cabinet. The arc light bursts at the speed of 300m/s and destroys any substance in the way. Arc light will always exist as long as uninterruptible power of the system. To minimize the harm of the arc light, we need a safe, rapid and effective semiconductor arc protection system. Arc light can reach 3m quickly within 10ms in the switch cabinet drawer, so the time is the main factor to minimize the losses. Bogmating arc protection system needs an extremely short time to output the trip signal and can protect the safety of the operators even during installation or maintenance.
