The HVPD Kronos® Spot Tester is designed for detecting Partial Discharge in all types of in-service plants.

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

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


Can be used on the following assets:

Compatible Sensors


HVPD Kronos® Ultimate Software

This software is driven through a PC for interpretation of your assets’ electrical insulation condition by measuring and distinguishing PD sources.

It features a number of reporting and analysis functions including, automatic report generation and the ability to view PD trends and phase resolved PD patterns.

Cable Mapping Analysis

The device can be used for on-line PD cable mapping to locate cable PD either single ended or double ended with the transponder.

MCSA Testing

To increase your ability in assessing a machine’s rotor/mechanical performance, the HVPD Kronos® Spot Tester has an add-on Motor Current Signature Analysis (MCSA) feature – non-intrusive, on-line test technique, used to assess the rotor condition of motors by analysing the frequency content of the current.

UHF Testing

Our UHF Converter is designed to be attached to the HVPD Kronos® Spot Tester and connected to UHF sensors such as the UHF Barrier Sensor to conduct for Partial Discharge in HV/EHV GIS.
