DESCRIPTION
The Megger Pinpointer model MPP2000 is specifically
designed to accurately and quickly pinpoint faults in
underground cable networks. Easy-to-access menus provide
advanced users the flexibility and features they desire.
The MPP2000 is housed in a lightweight, ergonomically
designed, rugged case that is IP54 rated. The unit can
be easily carried “hands free” using the adjustable neck
strap. In addition, the instrument can be used with any
manufacturer’s surge generator (thumper).
The MPP2000 is used to detect the acoustic and
electromagnetic fields. Both fields are generated by the
flashover at the point of fault, which has been generated by
the HV impulse caused by a surge generator. Detection is
via a lightweight ground microphone, which has a physical
shield to reduce external wind noise.
For easy interpretation, the receiver’s display shows clear,
unambiguous readings. The user interface features standard
directional and select arrow keys for easy navigation.
For operator comfort, and for use when the operator is
wearing a safety helmet, the MPP2000 is supplied with
“behind-the-head” headphones. Active noise-cancelling
headphones are available as an optional accessory.
Additionally the unit has a built-in “auto mute,” eliminating
all ambient noise, which is activated when the ground
microphone is raised from the ground.
The unit has an integral loudspeaker, the volume of which
can be adjusted for user comfort via the touchpad controls.
A single pushbutton “mutes” the output both on the
headphones and loudspeaker simultaneously.
The MPP2000 provides:
n
Detection of the acoustic discharge (“thump”) and
measurement of acoustic signal strength.
n
Detection and indication of the electromagnetic signal
strength.
n
Measurement of time delay between acoustic and
electromagnetic signals.
n
Indication of the direction to fault.
n
Calculated relative distance to fault.
APPLICATIONS
The MPP2000 pinpoints faults in underground power
cables using acoustic, electromagnetic and time delay
methods, enabling quick and accurate pinpoint location of
underground cable faults.
The location of the buried cable is indicated by the
intensity of the electromagnetic field produced by the HV
pulses of a surge generator. The bargraph indicator of the
MPP2000 shows a maximum intensity of the magnetic field
directly above the cable, reducing as the operator moves
away from the route of the cable.
Accurate and fast fault locating is accomplished using the
coincidence measurement of the acoustic signal, in time
relation to the electromagnetic signal produced at the
“flashover” or point of fault.
The receiver’s display shows the acoustic signal strength
and the time delay between the electromagnetic surge and
acoustic event.
When directly over the fault, the time difference is at a
minimum and the acoustic level is at a maximum. This is
especially useful when the cable is in a duct or pipe where
the acoustic signal could mislead the operator.
Behind-the-head headphones fit
comfortably even when worn
with safety helmet.
