PD Surveyor Air
Handheld PD Surveying tool for MV cable
and plants
The PD Surveyor Air™ is the rst line of defence for the de-
tection of PD activity in medium voltage (MV) power cables
and plants in voltage range from 6.6 kV to 45 kV.
The robust test unit, incorporating a digital TEV dB display
and external acoustic probes, enables the user to carry out
rapid, “look-see” insulation condition assessments through
the unique combination of three PD measurement technolo-
gies: HFCT, TEV and Airborne Acoustic.
The PD Surveyor Air™ test unit meets the requirements of
utility and industrial MV plant owners; this simple, portable,
handheld PD screening device can be used by all operational
staff in the substation, and is suitable for rapid PD screening
of MV metal-clad switch gears, cables and other types of
plants.
The PD Surveyor Air™ is recommended as a PD pre-screen-
ing tool to completely monitor the network. It is useful as a
precursor to more in-depth diagnostic testing, which is only
carried out if and when required (i.e. PD is detected by the
PD Surveyor Air unit). Examples of more in-depth diagnos-
tic tests include Online Monitoring with the sebaKMT LPD
Monitor and Of ine PD Diagnosis.

DESCRIPTION
Optional accessories are available to improve both the ex-
ibility and detection range of the PD Surveyor Air™ unit: the
outdoor acoustic parabolic receiver (incl. laser pointer) can
detect and locate surface/corona discharges on insulators or
outdoor terminations.
Online PD measurement on MV cable with the HFCT sensor.
