· Arch flash can be defined as, the production of light and heat due to the arc fault. It is a type of explosion due to the connection of air to the ground in an electrical system. Another reason for the arc flash is voltage phase etc. We explain it with an example, such as when a current-carrying wire makes a connection earthed system.
· An arc flash may be caused by many factors or events, such as: Unintentional tool contact with live parts. A tool dropped on the ground, which creates a spark which starts an arc discharge. Equipment failure due to poor maintenance or improper design. Use of non-sparking tools.
Arc Flash events cause operational downtime and, more importantly, can significantly damage energized equipment or personnel working nearby. DC Arc Flash Hazards Analysis module has been created to help users determine arc flash risk levels in DC networks and take necessary safety precautions.
