Electrical Thermography Services
Thermal image comparison: Original radiometric capture (left) and post-processed with optimized color palette (right) for enhanced visualization of temperature differentials.
Flexible electrical thermography services—from basic thermal imaging for quick inspections to NFPA 70B-aligned methods documentation. We tailor our approach to your requirements, whether you need quick anomaly screening or comprehensive condition reports for annual maintenance programs.
Capability status: This page describes what Aerial Accuracy would capture, review, and deliver for a commissioned electrical-thermography project. It is not presented as a record of completed electrical-thermography engagements.
The offering applies the same instrument control, measured field targets, and fail-closed review discipline used in our solar work.

NFPA 70B Alignment
NFPA 70B recommends annual electrical preventive maintenance inspections for facilities to maintain insurance compliance and operational safety. Our thermal inspections may support this recommendation by providing data that can help identify temperature anomalies for further investigation. (Note: NFPA 70B acceptance and insurance compliance requirements vary by facility and insurer—consult with your compliance officer.)
Facilities We're Prepared to Serve
- Cotton Gins: High-dust environments where thermal monitoring may help identify issues
- Grain Mills & Elevators: Electrical infrastructure monitoring for seasonal operations
- Food Processing Plants: Temperature anomaly identification to support fire prevention efforts
- Manufacturing & Industrial: Thermal data to support maintenance planning and downtime reduction
- Utility Substations: Safe, non-contact inspection of energized equipment (subject to utility approval and safety protocols)
What We Inspect
Transformers
Temperature anomaly screening that may indicate overheating or insulation issues
Switchgear & Panels
Thermal patterns that may suggest loose connections or circuit loading issues
Power Lines & Connections
Hotspot screening that may indicate resistance or connection issues
Motor Control Centers
Thermal patterns that may suggest bearing or electrical issues
Bus Bars & Breakers
Temperature monitoring to identify potential high-resistance connections
Circuit Breakers
Overheating patterns that may indicate capacity or internal issues
Our Process
We follow NFPA 70B guidelines to ensure the highest quality thermal inspection data:
- 1. Pre-Inspection Coordination: Load verification (minimum 40% capacity), safety protocols, site access arrangements
- 2. Thermal Data Collection: Systematic inspection of all electrical components with radiometric thermal imaging
- 3. Analysis & Severity Classification: Temperature delta measurements, severity ranking per NFPA guidelines
- 4. Professional Reporting: Detailed findings with thermal imagery, GPS coordinates, and maintenance recommendations
Deliverables
Our standard deliverable is a comprehensive report that includes:
- • Executive summary of critical findings
- • High-resolution thermal and RGB imagery of all inspected components
- • Detailed analysis of anomalies with severity classification
- • GPS coordinates for each defect location
- • Maintenance recommendations prioritized by urgency
- • NFPA 70B-aligned methods documentation
Important Scope & Expectations
Our thermal inspections follow the NFPA 70B framework and deliver professional temperature data and georeferenced thermal maps, providing a systematic screening tool for electrical preventive maintenance. We detect temperature anomalies that may indicate developing issues, helping you prioritize maintenance efforts and support maintenance documentation. Alignment is not certification or accreditation. Here's a transparent overview of our service parameters:
Engaging our services means you value this professional, NFPA 70B aligned approach to electrical preventive maintenance and safety documentation.
Critical Infrastructure Data Stewardship: We operate authorization-only at all electrical facilities. No imagery, coordinates, or metadata is published without written consent. See our Critical Infrastructure Ethics & Data Handling Policy aligned with Texas §423 and NERC CIP standards.
