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.
a gap between conductors. The result is an instant release of tremendous amounts of energy. Temperatures as high as 36,000ËF have been recorded in arc flashes. Hazards of Arc Flash/Blast â¢ The intense heat and light emitted by an arc flash can cause severe burns, destroying skin and tissue. An arc flash can ignite or melt clothing, resulting in further burns.
