DESCRIPTION
The prime objective of any cable fault location system is to
provide quick, effective, accurate and safe fault location,
thereby reducing system outages and “customer minutes
lost.”
The “new” family of compact Megger cable fault locating
systems is designed to meet this criterion. These new
systems are seen as a valuable extension to our existing
range of CFL instruments and capabilities.
The standard system comes as a mobile compact system
that can be further customised by the customer to meet
local requirements. All systems offer the facility to
undertake cable testing; cable and fault diagnosis;
prelocation of cable faults; fault conditioning; pinpoint
location using acoustic methods.

DC Testing (0-40 kV DC)
Used to prove the integrity of and to identify and confirm
fault conditions in cable networks with a test voltage up to
40 kV and a current of 25 mA. The variable output voltage
can also be used to test sheaths requiring 5 or 10-kV test
voltages. The operator selectable over-current trip levels
provide protection to the system under test in the event of
the cable under test breaking down.
Fault Pre-location
After identifying the type of fault, pre-location of the fault
position can be determined using the following methods:
■
In TDR mode, a real time trace and a stored trace can
be viewed simultaneously on the colour display,
allowing comparison and difference measurements to
be determined.
Standard Scope of Supply
TDR — The Time Domain Reflectometer offers:
■ Menu driven operation
■
User definable table of standard cable types
■
All pulse echo modes
■
Transient analyses methods of prelocation
In basic mode, the TDR features auto-ranging, auto
distance to fault and operator assist functions that guide
the operator through the fault locating process.
■
In the A.R.M. mode, faults are stablised by creating a
temporary “bridge” to earth. During this condition, a
standard pulse echo measurement is taken into what is
basically a short circuit fault.
■
ICE and Voltage Decay methods are both transient
analysis methods of pre-location which utilise either a
linear coupler or voltage divider. During a breakdown at
the point of fault, transients are generated that oscillate
both back to the TDR and far end of the cable. In ICE
mode, a surge generator (34 kV) max is used to
generate the breakdown; in voltage decay the dc source
(40 kV) max is used.
PFL — Portable Fault Locator provides:
■ D.C. testing
■
Fault conditioning
■ Proof/Burn
■ A.R.M. (Arc Reflection Method)
■
Fault pre-location using:
■ A.R.M. (Arc Reflection Method)
■ ICE (Impulse Current)
■ Voltage Decay
■
Acoustic pinpoint fault location
■
Ground Safety Interlock
The TDR is used to pre-locate cable faults using pulse
echo, arc reflection, impulse current (ICE) and the
optional voltage decay method.

Fault Conditioning
Fault conditioning is used to stabilise unstable, flashing or
high resistance faults. The Megger Fault Locator system
incorporates both A.R.M. and Proof/Burn modes.
■
■
Proof/Burn
Using the available 40 kV dc output and following a
breakdown of the cable under test, a high current is
applied, stabilising the fault condition. This allows
easier and quicker prelocation and pinpointing of the
unstable faults.
A.R.M.
Not widely thought of as a fault condition method, the
A.R.M. method stabilises faults by creating a temporary
“bridge” to earth, enabling standard pulse echo
techniques of prelocation to be used.
Acoustic pinpoint fault location
Accurate acoustic pinpoint fault location is achieved with
the powerful 8/16/34 kV (4 kV optional) surge generator
(thumper) which comes in either 1500 Joules or 2000
Joules (optional) configurations.
Additional accuracy can be achieved by using the Megger
MPP1001 or MPP1002 Acoustic and Electromagnetic
pinpointer, which shows direction and distance to fault.
