Thermal Imaging & Infrared Inspection in Pakistan.
TransfoLine delivers certified Thermal Imaging & Infrared Inspection Services across Pakistan using high-resolution FLIR and Testo thermal cameras. We inspect live HT/LT switchgears, power transformers, motor control centers (MCC), and busway connections under normal operating load to detect overheating joints, loose lugs, phase imbalances, and potential fire hazards before costly downtime occurs.
What is Electrical Thermal Imaging?
Electrical thermal imaging is a non-invasive diagnostic procedure that converts infrared radiation into high-contrast radiometric images to visualize temperature distribution across energized electrical components. By quantifying temperature differentials (ΔT), our certified thermographers detect loose bolted joints, contact oxidation, overloaded breakers, and transformer cooling blockages without interrupting factory operations.
Non-Invasive Live Load Inspection
Conducted safely while your facility runs at normal production capacity. There is zero electrical shutdown required, meaning zero lost manufacturing output for your plant.
Quantified Temperature Severity Reports
Every identified hotspot is documented with visual and infrared side-by-side images, ambient reference points, emissivity correction, and priority grading (Advisory, Intermediate, Serious, Critical).
Key Systems We Inspect in Industrial Facilities
NETA MTS Thermographic Evaluation Criteria
Our engineering reports categorize hot spots based on standardized temperature differentials (ΔT).
| Priority Level | Temperature Differential (ΔT) | Potential Fault Condition | Recommended Action |
|---|---|---|---|
| Class 4 (Advisory) | ΔT = 1°C – 10°C | Minor unbalance or incipient loose connection | Monitor during next routine scheduled maintenance |
| Class 3 (Intermediate) | ΔT = 11°C – 20°C | Loose bolted joint or significant phase unbalance | Repair within next available plant maintenance window |
| Class 2 (Serious) | ΔT = 21°C – 40°C | Severe terminal oxidation or localized overload | Correct promptly within 24 to 48 hours |
| Class 1 (Critical) | ΔT > 40°C / Temp > 100°C | Imminent flashover, insulation melting or fire danger | Immediate corrective action / Emergency shutdown |
Frequently Asked Questions.
Expert guidance on electrical thermal audits.
FREQUENCY How often should an industrial facility conduct thermal imaging?
Most industrial facilities and insurance providers require an annual electrical thermographic audit. For high-demand facilities such as textile mills, steel plants, and data centers, semi-annual scans are recommended.
EQUIPMENT Which thermal cameras does TransfoLine utilize?
We utilize calibrated FLIR E8-XT and Testo 875 professional thermal imagers equipped with MSX thermal enhancement technology, high thermal sensitivity (< 0.04°C), and wide temperature measurement ranges up to 550°C.
