Cable Fault Location
Cable Test Van Systems
The family of Megger Cable Test Vans was specifically developed with the demanding needs of our international customers in mind; may it be service contractors, utilities or research facilities. Our test vans are delivering superior performance, ergonomics, user-friendliness, reliability in the field and optimum speed on all 5 continents and even in difficult environmental conditions. Embodied into this unique test van concept are the requirements and the field experience of many end users. The result is a system which sets a new benchmark for cable fault location and cable diagnostics performance, empowering you to keep the power on.

System R 30 fault location system for all applications
The R 30 is suitable for challenging medium voltage and high voltage applications, thanks to its robust HV DC source, and its superior
energy discharge capabilities. The system is controlled with the single rotary knob easyGO interface of the Teleflex VX.
A number of high end options are available, e.g. DC test and Decay prelocation modules up to 150 kV and even 400 kV for UHV
transmission cables. The R 30 also offers surge generator options up to 100 kV, as well as ARM up to 50 kV and ICE up to 80 kV.
Time Domain Reflectometers TDRs
Advanced portable reflectometer for fault location systems Teleflex VX
Teleflex VX is especially designed to capture the rapid events
encountered during fault location in power cables. The new
hardware with significantly improved specification such as sampling
frequency, pulse width and pulse amplitude, offers a longer range,
higher resolution and above all, improved measurement.
Three-phase time domain reflectometer MTDR300
The 3-phase MTDR300 has a range from 100 m to 55 km is designed
to rapidly and accurately pre-locate faults in power cable networks.
Operation is via a single jog-dial and an easy-to-use menu with
pull-downs. All the operator has to do is select the operation and
click to confirm.
The MTDR300 is available as part of a Megger CFL or PFL system
and as a stand-alone unit, housed in a rugged field proven case.
Portable reflectometer for fault location systems Teleflex SX-1
With a range of between
20 m to 160 km Teleflex SX-1 is a
powerful TDR. It is easily operated
using the touch screen and control
knob and it automatically analyses the
trace to give the cable end and fault
distance indication. It supports all
existing pre-location technologies and
is compatible with all HV fault location
systems.
Overhead line testing system
This interface permits a Teleflex reflectometer to be safely attached
to overhead lines by earthing any dangerous induced voltages. By
measuring the impedance changes, it can detect breaks, short circuits
and branches off the line, smaller changes in impedance such as poor
connections, faulty insulators and changes in cross section and sags in
the line.
Single channel LV cable fault locator TDR1000/3P
A very capable TDR for identifying and locating faults on metallic
cables. The TDR1000 is suitable for use on both dead and live cables
without a blocking filter, up to CATIII 150 V phase-to-earth. Using
a 2 ns pulse the TDR1000/3P’s near end performance is exceptional
while offering a maximum range of 5 km.
Dual channel LV cable fault locator TDR2050
Offering a CATIV 600 V safety rating, the TDR2050 is perfect for chasing down fault
on power circuits such as street lighting. It is IP54 rated. The step function trace
improves the near-end performance of the TDR2050 as it prevents the trailing edge of
the pulse masking faults. Other features are Auto-find taking you to the major events
on the cable, Find-end function identifies the end of the cable and measures its length.
Distance dependant gain is a major benefit in long cable performance.
