PDS Insight™ 2

The NEW PDS Insight™ 2 is a portable, On-line Partial Discharge (OLPD) detection unit for mass rapid screening, that gives you the best early warning indicator of electrical insulation failure within your network.

Simple to use, the PDS Insight™ 2 can be placed in the hands of your technicians for the safe, reliable running of electrical assets (3.3 kV and above).

The Phase Resolved Partial Discharge (PRPD) feature in the PDS Insight™ 2 eliminates misleading background noise from the true partial discharge sources, which will help you to avoid in-service failures and costly, unplanned outages.

Deployed in phase 1 of our 4-phase asset management approach, Identify, the PDS Insight™ 2 is used to screen large electrical networks to quickly narrow down those assets in the worst condition - to target repairs and maintenance.

As standard, the PDS Insight™ 2 is supplied with a 10.1" Android tablet, running a dedicated On-line Partial Discharge (OLPD) application – the OLPD Manager™ app, which is also available for Windows, for the easy exporting of data and charts to maintenance reports.

The battery-powered unit stores all measurement data on its internal memory, which synchronises via Bluetooth to the OLPD Manager™ app. Both the unit and the app are available in 13 languages.

The PDS Insight™ 2 has a multitude of features which have been designed to support a range of maintenance planning strategies. They include:





  • Phase Resolved Partial Discharge (PRPD) for 'cleaner', more accurate PD readings.
  • Synchronise with the power supply frequency and generate 2D/3D PRPD patterns.
  • Incorporates three OLPD sensors: TEV, HFCT & AA.
  • Detects electromagnetic radiation from PD in metal-clad plant (TEV), current impulses from PD in cables and accessories (HFCT), and ultrasonic radiation from PD into air from air-insulated switchgear and other plant (AA).
  • Combines PD Level, PD Pulse Count and Cumulative PD Activity measurements across the 50/60Hz cycle.
  • An in-built barcode scanner is used with sensor POA barcode labels.
  • 10.1" Android™ tablet PC with the OLPD Manager™ asset management application.
  • Smart docking station for charging, data download and function checking of the unit.
  • Onboard data storage for quick testing and Bluetooth® communication to the Android™ Tablet PC
  • Measurements can be downloaded into a CSV file to enable filtering measurements and peak
  • RPD measurements can be displayed and recalled on the tablet. 
  • Asset operators and managers with multiple sites and multiple HVPD PDS Insight™ 2 units can back up and share data across all tablets to provide an asset management global view. 
  • 13 Languages options: English, Chinese, French, German, Polish, Portuguese, Russian, Korean, Spanish, Turkish, Vietnamese, Japanese and Arabic.


  • Easy-to-use, lightweight and portable handheld test unit.
  • The OLPD Manager™ app on the 10.1” Android™ Tablet PC makes it easy to setup a test record and to carry out repeat
    testing and monitoring.
  • Ensures the safe and reliable operation of HV networks, providing an early warning against incipient faults.
  • The unit’s barcode scanner retrieves sensor location ID from the Point of Attachment (POA) labels automatically. 
  • Optional accessories include the Outdoor Parabolic Receiver (for detecting corona and surface discharges in outdoor HV switchyards) and the Indoor Acoustic Search Probe (to extend the reach of the unit to detect airborne acoustic activity along the seams/ gaps in MV switchgear.
  • Asset operators and managers with multiple sites and multiple HVPD PDS Insight™ units can back up and share data across all tablets to provide a global asset management view.
  • All data between the PDS Insight™ handheld and the Android™ tablet is synchronised via Bluetooth®.
