HVPD Kronos® Spot Tester

Brand: HVPD
Model: HVPD Kronos® Spot Tester

New portable diagnostic test unit for detecting on-line partial discharge (OLPD) in all types of in-service plant, including cables, switchgear, transformers and rotating machines operating at 3.3 kV and above.

Product Information


The HVPD Kronos® Spot Tester is a 6-channel, synchronous, battery powered test unit with a rugged and compact design especially optimised for field portability.

Quick and easy to set up, it detects the early stages of insulation deterioration, providing an early warning against Medium Voltage (MV) and High Voltage (HV) insulation faults and supports condition-based maintenance (CBM) schemes, reducing unplanned outages, downtime and maintenance costs. 


Features and Benefits

  • Compact, robust and easily transportable system.
  • Battery powered: 8+ hours of operation for testing at remote locations without the need for a power supply.
  • Synchronous data capture on 6 channels enables advanced OLPD identification and noise separation for accurate PD diagnostic measurements in noisy environments and testing multiple assets at the same time.
  • Data acquisition and advanced diagnostic analysis is performed with HVPD Kronos® software.
  • Software displays data in real time, providing immediate feedback about the insulation condition.

HVPD Kronos® Software

The HVPD Kronos® software is used for data acquisition and analysis through to report generation. Data is acquired and presented in real time whilst statistical pulse wave shape algorithms identify PD and discriminate noise signals allowing the system to accurately identify and locate insulation faults. 

Various data analysis tools are available including Phase Resolved PD patterns, reports are generated automatically in Microsoft Word format. The software displayed left shows a phase resolved PD plot before and after de-noising with the HVPD Kronos® software.
