Additional Equipment for Power Fault Locating
Equipment
Acoustic/Electromagnetic
Surge Detector
The SD-3000 has been designed to pinpoint faults in
shielded, direct buried cables by detecting both the
electromagnetic and acoustic pulses emitted from an
arcing fault when it is surged. Either single or dual
detector configurations are available.
As a single
detector, the set provides detection of acoustic
emission, measurement of time delay between acoustic
and electromagnetic signals, and distance to the
fault. If a second detector is added, the set will
also display the direction to the fault. The SD-3000
can be used with PFL Systems or with surge generators
of other manufacturers.

Electromagnetic Impulse Detector
The Electromagnetic Impulse Detector has been designed
to localize faults on buried cable by detecting the
magnitude and polarity of current established on a
cable during surging with a surge generator.
The instrument is composed of an amplifier module,
sheath coil, and carrying case. It is typically used
on
network systems to isolate a fault between manholes.
An optional
earth frame and surface coil are available.
The Electromagnetic Impulse Detector can be used with
PFL Systems or with surge generators of other
manufacturers. |
