Condition assessment on switchgear

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.

A PD survey will:

• Reveal insulation weaknesses in MV & HV systems

• Increase reliability in MV & HV assets

• Increase asset longevity

• Increase safety

• Reduce Risk
• Reduce maintenance costs moving from preventive         to condition based-maintenance
