Lightning Strike Recorder (LSR)

have developed a Lightning Strike Recorder (LSR) which is designed for
easy mounting on a downconductor to effectively count the number of lightning
strikes captured by the Stormaster ESE Terminal.

The LSR has a current sensitivity range of 1500A through to a maximum of 220kA
@ 8/20µs impulse and operates by sensing current by means of an inductive
pickup loop. The strike recorder has a mechanical 6 digit display secured within a
polycarbonate IP 67 rated enclosure. The LSR is self powered and
does not require the use of a battery or any external power source.
Certified Performance
As one of the leading companies in the field of lightning protection,
has invested heavily in field and laboratory testing as part of
its on-going commitment to research and development.

Throughout the product development of the Stormaster ESE the

proto-type models were subjected to intense testing under high
voltage conditions. Following further refinements the Stormaster
terminals were subjected to final testing by an independently
accredited test laboratory which completed testing in full
compliance with the French National Standard NF C 17-102.
The final testing of Stormaster ESE terminals showed effective
performance as defined in the French National Standard.

The objective of the testing under NF C 17-102 is to

obtain a statistical result between a single reference
rod and the ESE terminal whereby a time
difference is obtained between the two and by
definition, a triggering time advance ∆T is
calculated. Safety margins are applied to
the measured values in order to provide
a conservative measured result.

dedicated low impedance lightning earth.

Ground Resistance
Improvement Powder (GRIP)
Ground Resistance Improvement Powder is an earth enhancing material
which is applied in and around an earthing system to reduce the soil
resistivity and lower ground impedance. GRIP is supplied in 10kg and
40kg kits and is particularly useful in difficult sites such as sandy soils
and rocky ground. LPI recommends the installation of a radial lightning
earth to aid in the efficient dissipation of the lightning energy.

Protection Performance
The protection radius (Rp) of a Stormaster ESE terminal is calculated using the Rp3
h1 Rp2
following formula as defined by the French National Standard NF C 17-102 (July Rp1
1995). h2

Rp = √h(2D-h) + ∆T(2D + ∆T) for ≥5m where:

h3
The following key parameters determine the calculation of RP.
• ∆T as established during the test.
Stormaster-ESE-15 = ∆T (µs) 15
Stormaster-ESE-30 = ∆T (µs) 30
Stormaster-ESE-50 = ∆T (µs) 50
Stormaster-ESE-60 = ∆T (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)
