Power Generation

We supply condition‑based assessment of MV and HV networks in the power generation industry with the main focus on on‑line partial discharge (OLPD) monitoring of large generators, motors and transformers rated from 3.3 to 15 kV, onshore and offshore.

Key Services

  • In‑service and factory PD testing of rotating machines' insulation
  • Remote on‑line PD monitoring of motor feeder cable circuits, including the motor stator windings using HFCT sensors located at the central switchboards of the network
  • OLPD monitoring of large MV generators with the HVPD Kronos® using HVCC sensors permanently installed in the generator's cable box


  • The HVPD Kronos® monitors distributed across the network continuously transfer the insulation condition data to the central HVPD OLPD Measurements Database© for logging, benchmarking and trending to identify the worst-performing circuits.
  • The central HVPD OLPD Measurements Database© holds data from all types of HV assets derived by HVPD from over twenty years of OLPD test experience and generates a simple OLPD Criticality number for the asset, from 0‒100%, through benchmarking and trending.
