Thermal imaging of electrical panels and installations in Seville, Spain

What thermal imaging of an electrical panel is for

Many burnt-out panels start the same way: a connection that worked loose over the years, a terminal that oxidised or a cable working above what it can carry. For months that spot runs hot without anyone noticing, until one day the breaker trips, an insulation melts or there is a smell of burning.

Thermal imaging of electrical panels lets you see that heat before it does any damage. We go over the panel with an infrared camera, and any point running hotter than normal shows up in the image. It is predictive maintenance: you repair while it is still cheap and without stopping your activity.

What a thermal imaging survey detects

• Loose connections on the terminals of breakers, RCDs and busbars.
• Overloaded protective devices: breakers working at their limit because the circuit has grown.
• Phase imbalance in three-phase installations, when one phase carries much more load than the others.
• Hot cables caused by an undersized cross-section or badly made joints.
• Deteriorated components: contactors, relays or fuses running hotter than they should.

Where we carry it out

• Apartment buildings and their communities of owners. Common services panels, lifts (elevators), pumps and garages. It complements building maintenance well and helps you reach a periodic inspection with everything in order.
• Shops, bars and offices. Commercial kitchens, cold rooms and air conditioning concentrate heavy loads on a few circuits. We see it often in premises in the city centre and Nervión, where installations have grown with every change of business. More on shops and offices and bars and restaurants.
• Warehouses and industrial estates. Main panels, machinery panels and power lines on the estates of Dos Hermanas, Alcalá de Guadaíra, La Rinconada or the north of Seville. It fits within industrial maintenance.
• Homes. When the fuse board gets warm, smells or a breaker trips for no obvious reason, especially in houses running air conditioning, an induction hob and an EV charger at the same time.

How we work

1. Preparation. You tell us how many panels there are and when they carry most load, because the survey is done with the installation running.
2. Visual and safety inspection. We open the covers with the necessary precautions and check the general condition.
3. Thermal images of every panel, with a normal photograph so each point can be identified.
4. Analysis. We compare temperatures between identical components and classify each anomaly by severity.
5. Report. You receive the images, the temperatures, the location of each fault and the priority for correcting it.
6. Correction if you want it. Re-tightening connections, replacing protective devices or rebalancing loads, with a prior quote. If the panel is badly deteriorated, a fuse board replacement may be the better option.

The method of thermography for condition monitoring of equipment is set out in the ISO 18434-1 standard. If the fault has already happened and the panel is damaged, what you need is an urgent repair from our 24-hour emergency electrician service.

A typical case

A restaurant in Seville notices that the kitchen breaker trips now and again in the middle of service, especially in August. The thermal images show a terminal on the kitchen RCD far hotter than everything else and one phase clearly more loaded than the others. The connection is re-tightened, the damaged terminal is replaced and the equipment is spread across the phases. The problem disappears without closing the restaurant for a single day.

Thermal imaging and electrical testing

The camera sees heat, but it does not measure earthing or cable insulation. For a complete diagnosis, combine it with electrical safety testing: earthing, insulation, loop impedance and RCDs.
