Detailed Technical Explanation

The WAT Franklin Plus is an advanced Early Streamer Emission (ESE) lightning conductor precision-engineered from corrosion-resistant austenitic stainless steel. Designed to operate autonomously without an external electrical power supply or radioactive sources, it harnesses the intensifying electrostatic field generated during thunderstorm conditions.

As downward stepped leaders approach from thunderclouds, the WAT Franklin Plus emits an upward streamer with precise timing advance (ΔT), establishing a controlled preferential discharge path before competing structural points can initiate unguided flashovers.

Constructed for extreme durability in aggressive tropical and coastal atmospheric conditions such as those in Kerala, it safely channels high-magnitude lightning discharges into the down-conductor network.
