PD Surveyor Air

The PD Surveyor Air™ handheld PD surveying tool is the 'first-line of defence' for the detection of PD activity in medium voltage (MV) power cables and plant in the voltage range 6.6kV to 45kV. 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.

Optional accessories are available to improve both the flexibility and range of detection of the PD Surveyor Air™ unit. With help from the optional available outdoor acoustic parabolic receiver (incl. laser pointer) it is possible to detect and locate Surface and Corona discharges on e.g. insulators or outdoor terminations.

Key benefits:

  • Three PD sensor technologies in one device
  • Early detection of PD activity
  • Universal application - can be applied to MV cables, switchgear & other types of MV plant
  • Directs maintenance resources straight to the problem areas
  • Easy to use
