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 require-ments 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 substa-tion. 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-screen-ing 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.
