Railway Electrical Protection
The consequences of an unexpected lightning strike
or power surge can­be c­ atastrophic for a facility:
As the railway industry becomes more dependent on increasingly
sensitive equipment, proper protection from lightning and dangerous
over-voltage transients is necessary.­
• Risk to personnel­
• Data can be corrupted
With more than 100 years of research, testing and product development,
ERICO has acknowledged that no single technology can totally eliminate
vulnerability to lightning and power surges.
• The costs of operational downtime and lost
revenue can be very substantial
The Six Point Plan of Protection from ERICO was designed to help
provide facility protection by integrating several concepts.
• Critical equipment may be damaged, or destroyed
The Six Point Plan will help
minimize the r­isk of damage to
facilities through:
Rail Six Point Plan of Protection
1
Capture the lightning strike.
4
Bond all ground points together.
2
Convey this energy to ground.
5
Protect incoming AC power feeders.
3
Dissipate the energy into the
grounding system.
6
Protect low voltage data/
telecommunication circuits.
• Direct Strike Protection
• Grounding and Bonding
• Surge and Over-Voltage

Direct Strike Protection
A more advanced approach to lightning protection is the ERITECH ®
SYSTEM 3000, which relies on the collection volume principle to
determine the effective placement of lightning protection to help ensure
the conveyance and d
­ issipation of the lightning energy into the ground.
ERICO’s innovative technology provides two systems for
capturing lightning ­­­energy. The ERITECH ® SYSTEM 2000
provides conventional air terminal technology to meet
traditional needs.
Thousands of facilities, including some of the most vulnerable buildings
in the world, are protected by the ERITECH SYSTEM 3000 from ERICO.

Grounding and Bonding
ERICO’s equipotential mesh, ground bars, signal
reference grids, ground pla­tes and Potential Earth
Clamps (PEC) help create a safe equipotential ground
plane for the protection of personnel and equipment.­
For the efficient performance of a lightning protection
system, it is essential that a low impedance ground be
provided to facilitate the dissipation of the lightning
energy into the earth mass.
Connections are often the most critical element of
grounding systems, so the preferred method of
connection is the CADWELD® exothermic
welding process.
As a grounding specialist, ERICO provides a range of
­grounding systems to suit any application.

Connections to the Rail
The CADWELD process
has been providing for a
wide range of cable sizes
and rail types for decades.
CADWELD is a molecular
bond which – when
properly applied – cannot
loosen, resists corrosion and
­­­produces a maintenancefree ­­electrical connection.
Tinned copper alloy bonds
allow for high tensile
strength and electrical
conductivity without being
attractive to theft.
With additional equipment
such as rail clips, drilling
machines and copper
inserts, ERICO can
supply various types of
connections to meet
specific requirements.

­­­­Power Protection
Modern electronics and circuitry used in signalling,
computing, communications and control/alarm
installations are highly susceptible to damage from
lightning surges and other transient over-voltages.
ERICO specializes in providing both primary and
secondary protection:
Primary Protection
At the point of entry of
power lines to buildings and
signal locations, high energy
shunt diverters rapidly limit
surges into the facility,
directing the excess surge
energy safely to ground.
The EPD120/240TDFL provides surge protection
that exceeds AREMA ® requirements and industry
standards. Specially designed for the railway industry,
the EPD incorporates patented surge protection
technology from ERICO, providing proven protection
from transient surges and electrical line noise.
• For sensitive electronic equipment protection,
or when high performance protection is required,
Surge Reduction Filters (SRF’s) are recommended. They reduce the peak
residual voltage to suitably low levels and dramatically reduce the rate of
current and voltage rise to downstream equipment.
The SRF family of products from ERICO uses suitably designed low-pass
filter technologies coordinated with shunt diversion stages incorporating­the
ERICO Transient Discriminating (TD) Technology. The coordination of each
of the above technologies within one package provides the ultimate hybridtechnology performance resulting in a robust surge rating and extremely
low residual voltages with a high Maximum Continuous Operating Voltage
(MCOV), designed to ­withstand sustained over-voltage conditions.
The EPD secondary protection products for both AC and DC power applications
help provide robust and reliable protection closer to the connected equipment.
Secondary Protection
The DIN-rail-mounted
SPDs, including shunt
diverter and series filter
models,­­provide various
levels of protection from
surges on power lines with
the convenience of easy
installation on 35 mm
DIN-rail mounting.
Signaling and
Telecommunications Protection
With the increased use of
sensitive electronics in
communications, signal and
data management, effective
surge clamping is essential
to prevent data corruption,
component damage,
operational downtime,
loss of revenue customer
dissatisfaction and risk to
human s­­afety.
