ELECTRICAL SAFETY
SOLUTIONS FOR SIGNAL
SYSTEMS AND TRACKSIDE
POWER INSTALLATIONS
Rail operators frequently experience faults in the electrical power
system that are caused by faulty connections, rodent damage,
breaks in insulation, re and cable theft. These faults may cause
earth leakage from the power supply which if left undetected or
addressed may lead to signal failure considerably compromising
the uptime availability of the rail network. Ultimately this results in
lengthy train delays, wasted engineer time and signi cant nancial
penalties for the operators.
In close consultation with Network Rail Bender has developed
an approved range of electrical safety equipment which detects
problems early and immediately informs rail personnel of defects.
Developing faults located in the system are identi ed in real time
and noti cation is provided directly into intelligent infrastructure
via GSM modem technology.
Rail Signalling (RS3) integrated insulation
monitoring and earth fault location
system The RS/PELI portable unit can also be used
to provide independent verifi cation of the
installed RS system performance. stage of system deterioration, avoiding
unplanned shutdowns and optimising
track availability.
The Rail Signalling (RS3) integrated
insulation monitoring and earth fault
location equipment provides proven
protection for railway electrical systems
and equipment up to AC650V. RS/IMD425 Insulation Monitoring System
single feeder cable systems The insulation monitor is designed for
Network Rail relay room and line side
location case installation and is supplied
with a weather protection housing and
insulated protective terminal cover
over the upper terminals. Each unit
incorporates as standard a GSM-enabled
data logger equipped for real time direct
communication with the Intelligent
Infrastructure.
Developed for relay rooms and line-side
locations, the RS3 system builds on the
impressive track record of equipment
approved by Network Rail for use across
the UK.
It is the fi rst system to incorporate
as standard GSM- enabled data
loggers equipped for real time direct
communication with the Intelligent
Infrastructure. It also delivers enhanced
reliability and simplifi ed installation and
commissioning.
The RS3 system’s ability to immediately
identify the location of the fault means
maintenance teams can respond more
rapidly, enhancing safety and reducing
downtime costs.
RS/PELI portable insulation monitor
The RS-PELI portable insulation monitoring
unit is designed to be used trackside to
measure and analyse specifi c sections of
the power network to prioritise installation
programmes.
The RS/PELI is self-powered through
connection to the trackside signal electrical
network and delivers live monitoring of
the system status to immediately indicate
if there is an earth fault and the status of
the insulation.
The RS/IMD425 provides insulation
monitoring and earth fault detection for
trackside signal power systems up to AC
300V. The unit provides engineering teams
with vital insulation resistance data that
enables planned maintenance at an early
stage of system deterioration, avoiding
unplanned shutdowns and optimising
track availability.
It is primarily installed on lower voltage
isolated power supplies -typically AC
230v- using single feeder cables but is also
suitable for AC/DC 12/24/50 and 120V.
The device off ers continuous insulation
monitoring of the power system to earth
with an adjustable alarm. Each unit
incorporates as standard a GSM-enabled
data logger equipped for real time direct
communication with the Intelligent
Infrastructure.
The unit is supplied fully factory tested
in a wall- mounted panel with a lock able
windowed door.
RS/IMD 265 Insulation Monitoring System
single feeder cable systems
The RS/IMD265 provides insulation
monitoring and earth fault detection
for trackside signal power systems up
to AC 650V using single feeder cables.
The unit provides engineering teams
with vital insulation resistance data that
enables planned maintenance at an early
The unit off ers continuous insulation
monitoring of the power system to
earth with an adjustable alarm and data
available for remote transmission to the
Intelligent Infrastructure.
Portable Earth Fault Location System
EDS3065
The EDS3065 portable earth fault location
system can be used to precisely locate
feeder earth faults line side, allowing the
repair process to be carried out more
quickly, minimising disruption to rail traffi c
and reducing system downtime.
The handheld unit is designed to pinpoint
a network earth fault to a specifi c cable
or transformer by detecting the test
signal from the RS3 system, and does not
require the cable or transformer to be
disconnected.
The unit simply clamps to the cable to
carry out the evaluation enabling spot
checks to discover whether a fault is
present in addition to pinpointing faults
identifi ed in the vicinity.
