The chief attribute of Early Streamer Emission Air Terminal is the generation of the continuous upward leader within its protected area. The functioning of ESE terminal is based on the electric characteristics of lightning formation. Lightning initiates with a downconductor, propagating in any direction. Once it approaches a close proximity to objects on the earth surfaces any of them can be struck. The objective of this Early Streamer Emission Air Terminal is to control the lightning strike point and provide the lightning current with a path to earth avoiding damage to the structure.
