PDS Insight™

The World's First On-line Partial Discharge Handheld Test Unit with an Asset Management Application – the OLPD Managerapp

The PDS Insight™, the world's first handheld On-line Partial Discharge (OLPD) test unit with a dedicated asset management tablet application – the OLPD Manager™ app. This unique, world-leading handheld test technology combines HVPD's knowledge from over 20 years of OLPD test technology development with the flexibility and functionality of the Android™ operating system and a 10.1" Tablet PC.
The PDS Insight™ measures PD Levels, PD Pulse Count and Cumulative PD Activity across the 50/60Hz power cycle to enable the severity of any partial discharge activity to be assessed. By combining three types of PD sensor (TEV, HFCT and AA), the unit is suitable for the OLPD testing of most types of in-service medium voltage (MV) cables and plant and OLPD surveying of outdoor high voltage (HV) switchyards. Suitable for OLPD testing of power cables, switchgear and transformers, the handheld unit stores all measurement data on its hard disk that is then synchronised via Bluetooth® to the OLPD Manager™ app for analysis, benchmarking and trending.


  • Compatible with three OLPD sensors: in-built TEV, AA and portable HFCT sensors.
  • 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 airinsulated switchgear (AIS) and other plant (AA).
  • Combines PD Level, PD Pulse Count and Cumulative PD Activity measurements across the 50/60Hz cycle.
  • Supplied with a 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 for post-test data analysis, benchmarking and trending.
  • All measurements can be downloaded into a CSV file to enable report writing and analysis.
  • The peak graph recorded with the HVPD PDS Insight™ can be displayed and recalled on the tablet. 
  • Supplied with Headphones.
  • Supports the use of multiple languages.
The PDS Insight™ represents a large leap forward in terms of handheld partial discharge test technology available in the market, it being the first handheld supplied with an accompanying data collection and analysis tablet PC application, the OLPD Manager™ app. With a built-in barcode scanner and unique point of attachment (POA) barcode labels, the new unit heralds a new generation of handheld OLPD test technology where measurement data can be automatically collected, downloaded and analysed quickly and easily using the OLPD Manager™ app on the supplied Android ™ tablet PC
