ESE LIGHTENING ARRESTOR

Early Streamer Emission (ESE air terminal , which operation is based
on the electrical characteristics of lightning formation. the air
terminal triggers the continuous upward leader earlier than any
other object within its protection area. this feature is called in the
standards “advance time” or “efficiency” of an ESE air terminal (T)
and determinates its protection radius. the earlier the upward leader
triggers, the larger is the distance where the downward leader is
intercepted, thus protecting a wider area against lightning.
