Detect overheating before failure
Thermal imaging of switchgear for businesses and property managers
Testing under actual load identifies connections, protective devices, and components requiring further diagnostics. The report describes conditions, location, priority, and recommended actions.
Thermal imaging shows temperature distribution — it does not replace measurements of protection, insulation, fault loops, or RCDs.
When it adds value
Where thermal imaging provides the most benefit.
- Switchgear supplies critical loads
- Installation operates under high or variable load
- Odour, discolouration, or signs of heating are present
- Protective devices operate without obvious cause
- The facility plans a shutdown or modernisation
- A preventive programme is needed for multiple switchgear units
- You want to combine thermal imaging with measurements and a repair plan
Conditions for a reliable survey
An electrical assessment, not just a colourful image.
- Documented load and ambient conditions
- Access to switchgear in accordance with H&S regulations
- Identification of field and device
- Correct emissivity and measurement geometry
- Comparison of components operating under similar conditions
- Confirming or remedial recommendation — not just a photo
Proof
A report that tells you what to do.
A thermogram without conditions and further action is not a maintenance programme — that's why the report includes context and priority.
- Possible cause described without undue certainty
- Priority: urgent, to be planned, to be observed
- Link to measurements and switchgear modernisation
- Object test history in the panel
Thermal imaging as an element of prevention.
The greatest value is created by the cycle: thermal imaging → diagnostics → repair → control measurement → history. For multiple switchgear units, we create a programme from this, not just a single photo.
FAQ
Questions about thermography.
Is the inspection performed under load?
Usually, yes – temperature distribution depends on the load. The report specifies the conditions and limitations of interpretation.
Is it necessary to shut down the installation?
The imaging itself takes place during operation, but safe access and potential opening of covers require a procedure and authorised personnel.
Does thermography replace electrical measurements?
No. It shows temperature distribution but does not replace tests for shock protection, insulation, fault loop, RCD, or power quality. Treat it as a supplement to measurements.
What determines the price?
The number and type of distribution boards, access, documentation, operating conditions, scope of the report, and potential combination with other measurements.
