The following is the degree of damage to the equipment caused by various arcing times as described in foreign materials:
—35 ms: There is no significant damage and it can generally be put into use after checking the insulation resistance.
—100ms: Less damage, cleaning or possibly minor repairs are required before the panel is put into operation again.
—500ms: The equipment is seriously damaged, and the personnel at the site are also seriously injured. Some equipment must be replaced before it can be put into operation.
Therefore, the time to cut off the arc fault is the key. Only the fastest arc protection system can provide the most effective protection. The goal of protection is to protect people's lives and property in the event of arc fault.
