Our thermographic inspections identify problems that visual inspections miss. A connection running 40°F hotter than normal won’t look different to the naked eye, but infrared cameras show the excessive heat that signals impending failure. We inspect electrical panels, switchgear, transformers, motors, and substations to catch issues early, when repairs are scheduled maintenance instead of emergency calls.
Insurance carriers, facility managers, and maintenance teams rely on our infrared inspections to prevent unexpected failures and extend equipment life. Our reports include thermal images, temperature readings, severity ratings, and repair recommendations formatted for engineers, insurance underwriters, and compliance documentation

Our Load Study & Power Monitoring Services
Our Electrical Thermography Services
Infrared Inspections & Thermal Imaging
Comprehensive thermal imaging surveys of electrical distribution systems, panels, switchgear, and connections. We use professional-grade infrared cameras to detect temperature anomalies, overheating components, and electrical issues invisible to visual inspection. Our surveys follow NFPA 70B guidelines and provide detailed documentation for insurance and compliance requirements.
Infrared Panel Inspections
Detailed thermal scans of electrical panels, circuit breakers, bus bars, and connections. We identify hot spots caused by loose connections, overloaded circuits, deteriorating breakers, and poor workmanship. Panel inspections prevent fires, reduce nuisance tripping, and catch problems before they damage equipment or interrupt operations.
Infrared Busbar Inspections
Thermal imaging of busbar systems in switchgear, panelboards, and electrical distribution equipment. Busbars carry high current loads, and loose connections or oxidation create dangerous hot spots. Our inspections identify overheating bus connections, phase imbalances, and deteriorating hardware before failure occurs.
Motor & Equipment Evaluation
Motor Evaluation
Comprehensive thermal analysis of electric motors, motor control centers, and motor-driven equipment. We assess motor health by detecting bearing failures, winding issues, phase imbalances, and cooling problems. Early detection prevents costly motor failures and production downtime.
Motor Bearing Thermography
Specialized infrared inspection of motor bearings to identify lubrication problems, misalignment, overloading, and bearing wear. Failing bearings show elevated temperatures well before catastrophic failure. Our inspections help maintenance teams schedule bearing replacement during planned downtime instead of responding to emergency breakdowns.
Motor Windings Inspection
Determine the actual demand factor for your facility based on real usage patterns rather than theoretical calculations. Helps optimize service sizing and avoid over-investing in electrical infrastructure.
Transformer & Substation Testing
Transformer Testing & Inspections
Infrared surveys of power transformers, distribution transformers, and dry-type transformers. We identify overheating connections, tap changer problems, cooling system issues, and internal faults. Transformer failures are expensive and disruptive; our inspections catch problems when repairs are still practical and affordable.
Transformer Bushing Inspections
Thermal imaging of transformer bushings, connections, and terminations. Bushing failures cause transformer outages and can lead to fires or catastrophic equipment damage. Our inspections detect overheating bushings, loose connections, and deteriorating hardware before failure occurs.
Transformer Load Tap Changer Inspections
Specialized infrared inspection of load tap changers (LTCs) to identify contact wear, poor connections, and mechanical problems. Tap changer failures disrupt voltage regulation and can damage transformers. Our inspections help maintenance teams schedule tap changer servicing before problems affect operations.
Switchgear Inspections
Comprehensive thermal surveys of medium-voltage and low-voltage switchgear, circuit breakers, contactors, and control circuits. Switchgear carries high current and voltage; failures can cause arc flash incidents, fires, and extended outages. Our inspections identify hot connections, deteriorating components, and phase imbalances before critical failures occur.
Substation Inspections
Comprehensive thermal surveys of medium-voltage and low-voltage switchgear, circuit breakers, contactors, and control circuits. Switchgear carries high current and voltage; failures can cause arc flash incidents, fires, and extended outages. Our inspections identify hot connections, deteriorating components, and phase imbalances before critical failures occur. Infrared inspections of electrical substations, including transformers, switchgear, circuit breakers, disconnect switches, and high-voltage connections. Substation equipment is critical infrastructure; failures can affect entire facilities or campuses. Our inspections provide documented equipment conditions and identify maintenance priorities for reliability programs.
If repairs or upgrades are identified during inspections, like panel replacements, breaker replacements, or electrical troubleshooting, our licensed electricians can handle the work and provide complete documentation.

The Right Solution, The First Time.
Why Infrared Thermography Prevents Failures
Electrical failures rarely happen without warning; equipment overheats for weeks or months before it fails. Infrared thermography detects those early warning signs when corrective action is simple and inexpensive. A loose connection that costs $200 to tighten today becomes a $15,000 panel replacement if it burns up next month.
A Phoenix manufacturing plant had their annual insurance inspection coming up. Our infrared survey found a main breaker terminal running 85°F hotter than adjacent connections, a clear sign of loosening hardware. We tightened the connection during a scheduled maintenance window, and the facility passed their insurance inspection without issues. That single finding prevented what would have been an expensive emergency repair and potential production shutdown.
Our thermography services meet NFPA 70B standards and insurance requirements. When you need load studies, NFPA 70B compliance documentation, or commercial electrical repairs, we provide complete solutions.
Frequently Asked Questions
Frequently Asked Questions
How often should we have infrared inspections?
Most insurance carriers and NFPA 70B guidelines recommend annual infrared inspections for critical electrical equipment. High-demand facilities may benefit from semi-annual inspections.
Do you need to shut down power for inspections?
No. Infrared inspections are performed on energized equipment under normal operating conditions. That’s when problems are most visible, the equipment must be carrying load to show thermal issues.
What's included in the report?
No. Infrared inspections are performed on energized equipment under normal operating conditions. That’s when problems are most visible, the equipment must be carrying load to show thermal issues. You’ll receive thermal images, temperature readings, severity ratings based on industry standards, and our recommendations for each finding. Reports are formatted for insurance carriers, engineers, and maintenance planning.
