⚡ What is a Lightning Arrester?
A Lightning Arrester (also known as a Surge Diverter) is a safety device used to protect electrical equipment from high-voltage surges, commonly caused by lightning strikes or power line switching. It redirects dangerous surges to the ground without affecting the power supply.
This essential lightning protection system is connected between the power line and the earth, and is placed in parallel with the equipment it protects.

🔥 Why Lightning Protection is Important in Kerala?
Kerala experiences intense lightning activity, especially during the monsoon season. Without proper protection, homes, buildings, and substations are at high risk of damage.
✅ We specialize in lightning arrester systems suitable for Kerala’s weather conditions and soil types.
🛑 Common Damages from Lightning Surges
Without a surge protection device (SPD), a lightning strike can result in:
Flashover inside transformer windings, damaging insulation.
External flashovers between terminals.
Burnt electrical insulators, causing breakdown or fire.

⚙️ How Does a Lightning Arrester Work?
When a lightning surge or travelling wave reaches the arrester:
It activates at a preset voltage level (spark-over).
A low-resistance path to ground is provided.
The surge is diverted safely, and normal operation resumes.
🔧 This fast response prevents expensive damage to electrical equipment, such as transformers, generators, and control panels.
✅ Features of an Ideal Lightning Arrester
⚡ No current flow during normal voltage
⚡ Instant response to surge voltage
⚡ Withstands high discharge currents
⚡ Self-restores quickly after the surge clears
