Also called a "'surge protection device "'( SPD ) or "'transient voltage surge suppressor "'( TVSS ), this class of device is used to protect equipment in power distribution systems . ( For consumer equipment protection, different products called surge protectors are used . ) The energy criterion for various insulation material can be compared by impulse ratio, the surge arrester should have a low impulse ratio, so that a surge incident on the surge arrester may be bypassed to the ground instead of passing through the apparatus.
