Kronos Spot Tester

Sophisticated diagnostic spot testing to protect your assets from failure

The 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 early stages of insulation deterioration, providing an early warning against MV and HV insulation faults. The Kronos Spot Tester supports condition-based maintenance schemes, reducing unplanned outages, downtime and maintenance costs.

Compatible Sensors:


Six Synchronous Channels

With synchronous acquisition on six sensors the Kronos Spot Tester can be used to test multiple assets at once in addition to comparing data from different sensors.

Test Using Pre-installed Sensors

Connect to any existing pre-installed PD couplers.

Cable Mapping

PD locations can be pinpointed along the length of power cables from one end of the cable (single ended) or with addition of the transponder at the far end of the cable (double ended).

Precedence Detection

Statistical PD pulse precedence detection to locate PD in MV metalclad air-insulated switchgear (AIS) by determining which sensor PD signals arrive at first.

Motor Current Signature Analysis (MCSA) Testing

With a current clamp connected to the Kronos Spot Tester, you can carry out MCSA to analyse the rotor condition of rotating machines, identifying issues such as damaged rotor bars and eccentricity. MCSA testing is non-intrusive and is carried out by analysing the frequency content of the 50/60 Hz current waveform.

Spot Testing and Short-Term Monitoring

The HVPD Kronos® Ultimate software is installed on a laptop for spot testing or Portable Partial Discharge Monitoring Server (PPDMS) for short-term monitoring. The PPDMS enables set-up of the monitoring session and data storage. Remote access to the system and cloud integration is possible via an optional modem.
