A surge arrester, surge protection device (SPD) or transient voltage surge suppressor (TVSS), is used to protect equipment in power transmission and distribution systems. The energy criterion for various insulation materials can be compared by impulse ratio. A 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.
Advantages of Protection Devices Protects electronic devices from hazards like short circuits and over currents. Reduces the risks of electric shock, injuries and fires. Keeps electrical
