Description

The PD Surveyor Air™ handheld PD surveying tool is the

"fi rst-line of defence" for the detection of PD activity in

medium voltage (MV) power cables and plants in the voltage

range from 6.6 kV to 45 kV. The robust test unit, incorporated

with a digital TEV dB display and external acoustic probes,

enables the user to carry out rapid, "look-see" insulation

condition testing through the unique combination of three

PD measurement technologies: HFCT, TEV and Airborne

Acoustic.

The PD Surveyor Air™ handheld test unit meets the requirements

of both utility and industrial MV plant owners for a

simple, portable, and easy-to-use hand-held PD screening

device that can be used by all operational staff in the substation.

It is suitable for rapid PD ‘screening’ of MV metal-clad

switchgear, power cables, and other type of plants.

The PD Surveyor Air™ is recommended as a PD pre-screening

tool for the 100% monitoring of the network. It is useful as

a precursor for more in-depth diagnostic testing, which is only

carried out if and when required (i.e. PD is detected by the PD

Sur-veyor Air unit). A more in-depth diagnostic test could be

for instance Online Monitoring with the sebaKMT LPD Monitor

or Offl ine PD Diagnosis.

Optional accessories are available to improve both the

fl exibility and detection range of the PD Surveyor Air™ unit.

With help from the optional available out-door acoustic

parabolic receiver (incl. laser pointer) it is possible to detect

and locate surface and corona discharges on insulators or

outdoor terminations.
