Thermographic inspection of electrical systems under load – with calibrated Fluke thermal cameras.
Overheating and loose connections found before they become failures.
For international operators of German sites we combine electrical thermography with the DGUV V3 inspection visit and document the findings so your maintenance team – and your insurer – can act on them. Reporting in English on request.
Benefits of thermographyDid you know?
Around 30% of all fires in industrial facilities have an electrical cause. Regular thermographic inspections can uncover these risks early and prevent fires.
Benefits of Thermography
Thermography is one of the most effective methods for preventive maintenance. It's fast, non-contact, and doesn't interrupt operations.
Early Detection
Spot defects and overloads before they cause failures or fires.
Cost Reduction
Avoid unplanned downtime and cut repair costs through timely maintenance.
Energy Efficiency
Find heat losses in buildings, piping, and equipment to reduce energy costs.
Non-Contact
Measurement without physical contact and without shutting down. Your production keeps running.
Documentation
Detailed reports with thermal images, temperature readings, and specific action items.
Fluke Precision
Calibrated Fluke thermal cameras only, for the highest measurement accuracy and reliability.
Where Thermography Makes a Difference
From electrical systems to mechanical components to building envelopes, thermography reveals weak points that are invisible to the naked eye. Qualified through the TÜV SÜD Akademie seminar “Thermografie an elektrischen Anlagen” (thermography on electrical systems); we work with calibrated Fluke thermal cameras.
Electrical Systems & Switchgear
Switchgear, distribution boards, transformers, fuses. Catch overheating and loose connections early.
Mechanical Equipment
Bearings, gearboxes, motors, couplings. Detect increased friction and wear through temperature anomalies.
Building Thermography
Locate thermal bridges, insulation defects, leaks, and moisture damage.
Photovoltaic Systems
Hot spot detection, defective cells, bypass diode failures, and connection problems.
Heating & Piping Systems
Locate blockages, leaks, and malfunctions without contact.
Process Monitoring
Monitor temperature distribution in production processes and optimize parameters.
PV Thermography. Find hidden power losses.
Thermographic testing of PV systems is one of our specialties. Defects often go unnoticed for a long time and cause gradual performance degradation.
Hot Spot Detection
Localized overheating of individual cells, indicating cell defects, shading, or soiling.
Defective Bypass Diodes
Faulty bypass diodes produce characteristic heat patterns that are clearly identifiable via thermography.
Connection Problems
Loose or corroded connectors create contact resistance that shows up as heat sources.
String Failures
Failed strings show clearly different temperature profiles compared to functioning strings.
Tip: We recommend combining PV thermography with a DGUV V3 test of the PV system. Thermal and electrical testing in one visit.

Industries That Rely on Thermography
Frequently Asked Questions about Thermography
Industrial thermography uses thermal imaging cameras for non-contact surface temperature measurement under load. We measure with calibrated Fluke thermal imagers. This makes increased contact resistance, overload, and wear visible before they cause a failure – without interrupting operations.
Thermography is used on electrical systems, switchgear and distribution boards, on mechanical components such as bearings, gearboxes and motors, on building envelopes, and in preventive maintenance of production plants.
Qualified through the TÜV SÜD Academy: thermography on electrical installations. Measurement and assessment are carried out by a qualified electrician – important because findings in switchgear must be evaluated electrically, not just photographed.
Effort depends on the number of cabinets and distribution boards, accessibility, and the load condition we can schedule. Fixed-price offer after a site visit or assessment – no hidden items. The initial consultation is free.
For heavily loaded switchgear and distribution boards, an annual cycle has proven itself – many property insurers require it. The decisive factors are system condition, load, and your insurer’s requirements.
