LPI Stormaster ESE
The LPI Stormaster ESE range of terminals provides a safe and efficient system for the protection of your facility from direct lightning strikes. The LPI Stormaster ESE terminal captures the lightning energy at a preferred point.
The energy is conveyed to ground via downconductor(s).When the energy enters the dedicated lightning earth, it is safely dissipated without risk to personnel and equipment.
How does the LPI Stormaster ESE Terminal work
The Stormaster Early Streamer Emission air terminal uses the naturally occurring electrical field to complete the timely release of an upward streamer. This process provides for a safe and efficient method of controlling dangerous lightning energy at a preferred point.
As a thunder storm gathers overhead the ambient electrical field surrounding the Stormaster ESE begins to rise in voltage. Upon the approach of a downleader towards the protected area there is a rapid increase in the electric field
which initiates the triggering of an upward streamer from the Stormaster ESE terminal. The concept of earlier allows for a larger or enhanced area of protection to be provided by the Stormaster ESE in comparison to a conventional rod.
With the release of the upward streamer from the finial tip earlier than other competing structural points, the Stormaster ESE terminal becomes a preferred point for the capture of the lightning discharge within the protected area.
LPI offers four models in it is range of Early Streamer Emission air terminals.
All terminals have been tested to NF C 17-102.

The protection radius (Rp) of a Stormaster ESE terminal is calculated using the
following formula as defined by the French National Standard NF C 17-102 (July
1995).
Rp = √h(2D-h) + ΔT(2D + ΔT) for ≥5m where:
The following key parameters determine the calculation of RP.
ΔT as established during the test.
Stormaster-ESE-15 = ΔT (μs) 15
Stormaster-ESE-30 = ΔT (μs) 30
Stormaster-ESE-50 = ΔT (μs) 50
Stormaster-ESE-60 = ΔT (μs) 60
h = actual height of Stormaster terminal above the area to be protected (m).
D (in m) depends on the selected level of protection, protection
levels are specified in annex B of the standard NF C 17-102.
D = 20m for protection level 1 (High Protection)
D = 45m for protection level 2 (Medium protection)
D = 60m for protection level 3 (Standard protection)
