NFC 17 102 is the International Standard that governs the use of Early Streamer Emission systems (ESEs). These are an alternative to the Faraday Cage system, which many consider the conventional type of lightning protection system, and which are governed by IS EN 62305:2011. The ESE is a lightning rod with an electronic streamer emission device that uses the atmospheric gradient to store energy. This subsequently emits high frequency pulses to the atmosphere which creates a priority channel for the lightning discharge, known as the upwards leader. The ESE head captures the lightning strike and safely dissipates the current through the down conductors and into earth.
