Students could look at the rapid changes to society that the invention of the internal combustion engine led to. The most obvious intervention was the car. How did the car change the lives of those who could afford one? How did Henry Ford's new manufacturing methods improve the speed of assembly and reduce the cost of production?
Arc Flash is the result of a rapid release of energy due to an arcing fault between a phase bus bar and another phase bus bar, neutral or a ground. During an arc fault the air is the conductor. Arc faults are generally limited to systems where the bus voltage is in excess of 120 volts.
Arc Flash Analysis with Electrical Testing Solutions. Explosive energy released during arcing faults will send more than 2,000 workers to burn centers this year. In addition, of approximately 350 persons killed in the work place by electricity last year, roughly 50% were related to arc flash.
