A fault announces itself with heat
Most electrical faults in companies do not come out of nowhere: a loose terminal, an untightened busbar bolt, an overloaded phase, or an aging contactor first heat up for weeks - and only then burn, shut down the production line or the entire facility. A thermal imaging camera sees this "heating up" stage from a safe distance, without switching off the power supply 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 distribution boards - terminals, devices, busbars, cables;
- Loads - drives, motors, transformers, capacitor banks, cable routes;
- Without downtime - the inspection does not require shutdowns; a short window agreed with maintenance is enough to remove the covers.
What you get in the report
The report is not a gallery of colourful pictures. Each anomaly has a thermogram + photo + location + measured temperature difference and a priority:
- immediate - a defect threatening a failure or fire; it can usually be fixed on the spot (tightening, replacing the device) during the next maintenance window;
- scheduled - to be rectified within an agreed period before it grows;
- observation - a point for comparison during the next inspection.
This makes the report an immediate action plan with priorities - and the subsequent test shows the trend, not just the current state. Service details for businesses: thermal imaging of switchgears and installations.
Not only industry
Thermal imaging also works great in residential buildings: floor distribution boards, service connections and main power lines (WLZ) in older blocks of flats are classic places where the camera finds heating connections long before a failure occurs. For property managers, we combine it with the five-year inspection - one date, complete knowledge of the building.
When to test
- before the peak load season (winter - heating, summer - cooling and peak production);
- after modernising the switchgear or changing loads (new machinery, new production line);
- cyclically, as part of a service agreement - this is also required by some property insurers.
The math is simple: a fault found with a camera costs as much as the test and tightening the terminal. The same fault on Friday at 22:00 costs downtime, emergency service and stress. We invite companies to check our B2B offer - from a single test to permanent service with SLA.
