Optimum protection of LV switchgear with respect to arcing faults.

      Аннотация: An arc flash event may be really harmful to people who interact with electrical installations and could cause significant damage to equipment and facilities. The incident energy from an arc flash should be measured in accordance with existing standards, their risks must be controlled and attenuated, in order not to compromise the physical integrity of people and facilities. With the evolution of studies involving the arc flash, the market starts to develop several solutions to mitigate the arc effects. This paper judges which is the best way to protect Low-Voltage switchboards against arcing incidents, regarding to the optional use of the insulated busbars.
