WebAn arc flash is the light and heat produced from an electric arc supplied with sufficient electrical energy to cause substantial damage, harm, fire, or injury. Electrical arcs experience negative incremental resistance, which causes the electrical resistance to decrease as the arc temperature increases. Therefore, as the arc develops and gets hotter the resistance … WebRelay A can directly trip both its Main and the tie breaker. Relay B trips its Main and uses a high-speed digital output to make Relay A open the Tie Breaker. In the event of an arc flash in the tie breaker cabinet, both mains must be tripped. Here, Relay A will trip its Main and use a digital output to make Relay B trip Main Breaker B. khadi ayurvedic hair oil
