A Fault Announces Itself with Heat
Most electrical failures in companies don't come out of nowhere: a loose terminal, an untightened busbar screw, an overloaded phase, or an aging contactor first heat up for weeks — and only then do they burn out, shut down a production line or an entire facility. A thermal imaging camera sees this "heating up" stage from a safe distance, without switching off power and without dismantling the distribution board.
What the Inspection Looks Like
- Under real load — we inspect when the facility is operating normally; an empty distribution board will show nothing, as problems only reveal themselves under current;
- Main and branch distribution boards — terminals, apparatus, busbars, cables;
- Receiving points — drives, motors, transformers, capacitor banks, cable routes;
- No downtime — the inspection does not require shutdowns; a short window agreed with maintenance is sufficient to remove covers.
What You Get in the Report
The report is not just a gallery of colourful images. Each anomaly includes thermogram + photo + location + measured temperature difference and priority:
- immediate — a fault threatening breakdown or fire; usually can be fixed on the spot (tightening, replacing equipment) at the nearest service window;
- scheduled — to be rectified at an agreed date, before it escalates;
- observation — a point for comparison in the next inspection.
This way, the report immediately becomes a repair plan with priorities — and the next inspection shows a trend, not just a state. Service details for businesses: thermography of switchboards and installations.
Not just industry
Thermography also works great in residential buildings: floor distribution boards, connections and main supply lines (WLZ) in older blocks are classic places where the camera finds overheating connections long before a failure. For property managers, we combine it with a five-year inspection — one appointment, complete knowledge about the building.
When to inspect
- before the season of highest load (winter – heating, summer – cooling and production peak);
- after switchboard modernisation or load changes (new machines, new line);
- periodically, as part of a service agreement — also required by some property insurers.
The calculation is simple: a fault found with a camera costs as much as the inspection and tightening of a terminal. The same fault on Friday at 10:00 PM costs downtime, emergency service, and stress. We invite companies to our B2B offer — from a single inspection to ongoing service with an SLA.
