1.5.4 Lightning Protection
DANGER
Lightning strikes can cause severe damage to structures, devices, services and
human life. Therefore it is essential to consult an authorised specialist to
design and install a means for reliable and efficient lightning protection.
The protection must consider all elements of your receiver installation, that is:
•Devices, for example receiver, GNSS antenna, meteo stations, radio com-
munications (cellular mobile, terrestrial), switches, routers
•Power lines
•Signal lines, for example from an antenna
•Communication and data lines, for example Ethernet or serial
•Structures, for example building, mast, cabinet
•Solar panels
Lightning may ignore every defence man can conceive. A systematic hazard
mitigation approach to lightning safety is a prudent course of action.
The warranty of the receiver does not apply to, and Leica Geosystems is not
responsible for defects, malfunctioning or performance issues resulting from:
Warranty exclusion
Safety Directions 13

•Damage caused by lightning or any other electrical discharge.
Lightning Protection Zones (LPZ) can be divided into:
Zone Description
External
LPZ 0A, LPZ 0B
Zones which are at risk from direct lightning strikes,
from impulse currents up to the whole lightning cur-
rent and from the whole electromagnetic field of the
flash of lightning.
Internal
LPZ 1...n
Zones where impulse currents are limited by splitting
the current and by Surge Protective Devices (SPDs)
at the zones boundaries. The electromagnetic field
of the lightning flash can be attenuated by spatial
shielding.
At the boundary of each internal zone, the equipotential bonding must be car-
ried out for all metal components and utility lines entering the building or
structure. Equipotential bonding is done directly or with suitable SPDs.

An Active Lightning Protection (ALP) System combines protection with lightning
detection.
Functionality
•Carrying out preventive measures in advance
•Triggering an early streamer of ionised air.
The streamer intercepts lightning discharges for the safe passage to a low
impedance down-conductor.
Leica customers reported successful application using products from:
•Lightning Protection International Pty Ltd (www.lpi.com.au)
A Passive Lightning Protection (PLP) System and an ALP are similar.
The PLP System has no detection (preventive measures) or triggers for an early
streamer.
Leica customers reported successful application using products from:
•Huber and Suhner (www.hubersuhner.com)
•Polyphaser (www.protectiongroup.com)
A down conductor system consists of a bonding network that covers the outer
face of a structure, for example building.
Active Lightning Pro-
tection System
Passive Lightning Pro-
tection System
Down conductor sys-
tem
Safety Directions 17

In a steel-reinforced concrete structure, the reinforcement of the outer walls
can be used as natural components.
Structures made of insulating material, for example wood or bricks, need an
extra bonding network as down conductor system.
As part of the external LPS, an earth termination system for grounding must
address low earth impedance.
Suitable for grounding are poles or depths/plate/ring earth counterpoises.
Disadvantages
•Corrosions depending on the soil conditions
•Damage due to excavation
Corrective measure
Use a foundation grounding rod. Such a rod is required for electric facilities in
and at structures, for example building, pillar or mast.
The foundation grounding rod is built into the concrete foundation of the
structure.
Any incoming connection into a building that can transfer an electrical potential
from outside to inside must be protected against electrical discharge.
Recommendation
Deploy an EBB which is properly connected to the grounding system at the
building and/or cabinet entry point.
Part Example
Incoming connection into a building Water, gas, communication, data or
power line
Electrical discharge Lightning surge
Case
A cabinet box is used to protect the receiver and electronic against environ-
mental impacts.
Recommendation
Use a structural separation with a metal partition panel within the cabinet.
Purpose of a structural separation
•Separation of lightning protected and not protected part of the cabinet
•Avoiding crossed cables originating from the lightning protected and not
protected part of the cabinet
•Attenuation of transient and magnetic induced fields
