Electrical panel thermography is a highly effective diagnostic technique used to identify hidden thermal abnormalities in energized electrical systems. By using advanced infrared imaging, this inspection helps detect issues such as overheating, loose connections, and load imbalances before they result in system failures or safety hazards.
At Voltix Conseng, we provide professional thermographic inspection services for electrical panels across industrial, commercial, and infrastructure facilities, ensuring early fault detection and improved system reliability.
What is Electrical Thermography Inspection?
Electrical thermography inspection is a non-contact, infrared-based evaluation method used to analyse temperature variations in live electrical equipment. It allows engineers to assess system performance without interrupting operations.
Why Electrical Thermography is Important
- Detect potential failures at an early stage
- Reduce fire risks and electrical hazards
- Prevent unexpected downtime and shutdowns
- Support predictive and preventive maintenance strategies
Scope of Inspection
Our thermographic inspections typically cover:
- LT panels, MCC, PCC systems
- Busbars, joints, and cable terminations
- Transformer connections and switchgear
- Systems under electrical load and performance evaluation
All inspections are carried out under normal operating conditions, ensuring real-time detection of issues.
Common Issues Identified
Through thermographic analysis, we commonly detect:
- Loose or deteriorated connections
- Overheating components and joints
- Phase imbalance and uneven load distribution
- High resistance points and abnormal heat signatures
These issues are identified based on temperature differentials (ΔT) compared to similar components under similar operating conditions.
Inspection Methodology
Thermographic scanning is conducted while systems are energized and under load. Our engineers perform detailed infrared scanning across all critical components, including panels, joints, terminations, and connections.
Thermal images are analysed by comparing:
- Phase-to-phase temperature variation
- Component-to-component differences
- Ambient temperature reference
Any abnormal temperature rise is evaluated to determine the severity and associated risk.
Instruments & Technology
We utilize high-precision infrared thermal imaging cameras (such as FLIR, Fluke, and Testo), calibrated as per industry standards. These instruments ensure accurate measurement and repeatability for reliable diagnostics.
