Commissioning​ of CT & VT
Commissioning is a systematic process of verifying newly-installed, refitted equipment or systems before it is put into service. It is performed to ensure that the system operates according to its design, and to confirm the intended safety and reliability.
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
