Condition assessment on transformer

Condition assessment provides knowledge about the state of the various components in HV grids. This knowledge contributes to the right decisions regarding maintenance and replacement.

Condition based-maintenance improves the overall performance at a lower cost

Online PD Survey


Partial discharge (PD) is regarded as the best early warning indicator of insulation degredation in MV & HV assets.

The PD survey reveals and locates faults without service interruption. This is a complex PD survey which captures the PD pattern with it`s waveform and the frequency spectrum of every PD pulse that the fault generates. This provides the complete information regarding the activity so that appropriate measures can be taken


The survey is suitable for any electrical equipment from 3kV to 600kV.

PD survey will:

  • Identify insulation weaknesses in transformer and bushings

  • Increased reliability of high voltage components

  • Increased service life

  • Increased sefety

  • Reduce risk

  • Reduce maintenance costs
