· 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.
Arc faults are generally limited to systems where the bus voltage is in excess of just 120 volts, and with 5 to 10 arc flash incidences occurring every day in the US alone, makes Arc Flash an extremely relevant, important and in most instances a regulatory required issue that must be controlled.
The energy formula for an arc flash is: Energy = voltage x current x time. For a given system voltage, two factors can be adjusted to reduce arc-flash energy: time and current.
