Terms of Warranty
Megger accept responsibility for a claim under warranty brought forward by a customer
for a product sold by Megger under the terms stated below.
Megger warrant that at the time of delivery Megger products are free from manufacturing
or material defects which might considerably reduce their value or usability. This
warranty does not apply to faults in the software supplied. During the period of warranty,
Megger agree to repair faulty parts or replace them with new parts or parts as new (with
the same usability and life as new parts) according to their choice.
This warranty does not cover wear parts, lamps, fuses, batteries and accumulators.
Megger reject all further claims under warranty, in particular those from consequential
damage. Each component and product replaced in accordance with this warranty
becomes the property of Megger.
All warranty claims versus Megger are hereby limited to a period of 12 months from the
date of delivery. Each component supplied by Megger within the context of warranty will
also be covered by this warranty for the remaining period of time but for 90 days at
least.
Each measure to remedy a claim under warranty shall exclusively be carried out by
Megger or an authorized service station.
This warranty does not apply to any fault or damage caused by exposing a product to
conditions not in accordance with this specification, by storing, transporting, or using it
improperly, or having it serviced or installed by a workshop not authorized by Megger.
All responsibility is disclaimed for damage due to wear, will of God, or connection to
foreign components.
For damage resulting from a violation of their duty to repair or re-supply items, Megger
can be made liable only in case of severe negligence or intention. Any liability for slight
negligence is disclaimed.

For this reason, it is important to ensure that the manual is always available to
authorised and trained operating personnel. Operating personnel should read the
manual thoroughly. The manufacturer will not be held liable for any injury or damage to
personnel or property through failure to observe the safety precautions contained in this
manual.
The specific standards and regulations in each country must also be observed!

Description
DANGER Indicates a potential hazard which will result in death or serious
injury if not avoided.
WARNING Indicates a potential hazard which may result in death or serious
injury if not avoided.
CAUTION Indicates a potential hazard which may result in moderate or
minor injury if not avoided.
NOTICE Indicates a potential hazard which may result in material damage
if not avoided.
Serves to highlight warnings and safety instructions.
As a warning label on the product it is used to draw attention to
potential hazards which have to be avoided by reading the
manual.
Serves to highlight warnings and safety instructions that explicitly
indicate the risk of an electric shock.
Serves to highlight important information and useful tips on the
operation of the device/system. Failure to observe may lead to
unusable measurement results.
It is important to observe the generally applicable electrical regulations of the country in
which the device will be installed and operated, as well as the current national accident
prevention regulations and internal company directives (work, operating and safety
regulations).
Use genuine accessories to ensure system safety and reliable operation. The use of
other parts is not permitted and invalidates the warranty.
This system and its peripheral equipment may only be operated by trained or instructed
operating personnel. Anyone else must be kept away.
The system may only be installed by a specialist electrician. DIN VDE 0104 (EN 50191),
DIN VDE 0105 (EN 50110) and the German accident prevention regulations (UVV)
define a specialist electrician as someone whose knowledge, experience and familiarity
with the applicable regulations enables him to recognise potential hazards.

2.1 System description
The indicator unit can be used for different measuring tasks depending on the
measuring accessories connected. Which of the following sensors and antennas
actually belong to the delivery (see page 9) depends on the set purchased:
Surge wave receiver DPP-SU2
for the accurate pinpointing of
flashover faults in buried cables
A discharge generator feeds surge voltage pulses into the end
of the
faulty wire. These cause voltage arc-
overs at the fault location. The
resulting flashover noise propagates in the ground and is recorded with
the surge wave receiver on the surface. The distance to the fault
location can be calculated using either t
he volume of the flashover noise
or the time difference between the arrival of the magnetic pulse and the
flashover noise.
Audio frequency receiver iFS
for route tracing and fault location on
buried metallic lines.
With the aid of the antennas, the al
ternating current flowing in metallic
lines can be recorded, converted into a signal and transferred to the
indicator unit.
In this way, as well as metallic lines which are transmitting
a signal from a suitable transmitter (491 Hz … 33 kHz), cables that ar
e
operational (50 / 60 Hz) and pipelines carrying a current of 100
Hz /
120
Hz current for protection from corrosion can be located and traced.
For lines carrying an active signal generated by an audio frequency
generator not only the path but also the lay
ing depth, the current
strength and the direction of signal flow (in case of a SignalSelect
encoded signal) can be determined.
Earth spikes for accurate pinpointing of sheath faults on plastic
insulated PE and VPE medium voltage cables
Sheath faults are pinpointed using the step voltage method. The
measuring current flowing into the ground at the fault location forms a
potential gradient forms at the point of escape, which is measured using
earth spikes and the downstream indicator unit. The step voltage rises
when both earth spikes are situated in front of the fault position. If the
fault position is passed by, the step voltage polarity changes, which then
subsides again the further away you go.
Reader coil IFA for identifying a cable among several ac
cessible
cables
As with the iFS
receiver, the reader coil is used to detect audio
frequency signals within the frequency range of 50 Hz to 33 kHz. In
contrast to the receiver, the coil is applied directly onto the accessible
cable, thus increasing the meas
urement accuracy. Thanks to
SignalSelect compatibility, this method also ensures the reliable
identification of a cable on which a SignalSelect signal is transmitted
(e.g. when a cluster of cables is exposed after excavation work).
