GIS & Switchgear Partial Discharge Testing
DigiStano provides partial discharge testing and diagnostic support for GIS and MV/HV switchgear. The assessment is planned around the switchgear design, available measurement points and whether the equipment can be taken out of service.
Plan the measurement
Start with the asset and the question.
Tell us whether you are preparing for commissioning, investigating a concern or establishing a condition baseline.
- Switchgear manufacturer, model and rated voltage
- Number of bays, panels or compartments
- Available sensor ports and previous survey results
- Site access and permitted outage windows
Engineering scope
From the test plan to the findings.
Review
Review asset information and previous diagnostic evidence.
Plan
Agree the measurement scope, access and responsibilities.
Assess
Review observed activity with relevant test or operating conditions.
Explain
Discuss observations, limitations and suitable follow-up.
Project requirements
A scope you can review before the visit.
Agree the assets, measurement approach, access, applicable project specifications and reporting requirements.
Can GIS and switchgear be assessed while energised?
Online assessment may be possible where the installation provides suitable measurement access and the site permits the work. Sensor installation or additional testing can still require an outage. The engineering team confirms this during scope review.
What should the report address?
Agree the reporting requirements in the proposal: asset identification, test arrangement, relevant conditions, observations, interpretation, limitations and recommended follow-up.
Before you request testing
Prepare your PD testing request
Use our checklist to share the asset details, access constraints and objective so the engineering team can scope your assessment accurately.
