Lightning Arrester

Advantages

• Absorbs switching surges caused either due to load rejection, system faults & clearing or line energisation/de-energisation.
• Excellent protection characteristic against temporary over voltage arising from either earth faults, load rejection or resonance and ferro-resonance.
• Better thermal stability and efficient dissipation of energy due to eccentric assembly of MOV blocks individually supported by silicon rubber support and strip.
• Simple rugged construction prevents internal arrester damage during shipping and installation.
• Ensures longer life due to hermetic sealing of the arrester.
• Pressure relief system prevents explosive failure of the arrester housing in the event of prolonged passage of fault current of internal lash over of the arrester.
• No maintenance except cleaning of the arrester housing.
• Design type testing of lightning arrester is in according with international standard IEC 60099-4 and IS 3070-part 3.
