NFPA 70B Substation & Power Grid Thermography
NFPA 70B is a standard for electrical-equipment maintenance. Its applicability and inspection frequency depend on the facility's program and qualified electrical authority. We provide regional thermal screening and documentation for qualified review.
ERCOT Grid Stress Response
During extreme temperature events—like prolonged West Texas summer heatwaves or Winter Storm Uri conditions—the electrical grid operates at maximum load. This is exactly when transformers, switchyards, and transmission lines are most likely to show critical thermal anomalies.
The Local Utility Advantage: When utility internal resources are overwhelmed responding to active outages, you cannot wait two weeks for out-of-state drone contractors to mobilize. Based in the Panhandle, Aerial Accuracy deploys high-voltage thermal imaging promptly during peak-load events to flag visible surface-temperature anomalies for qualified review. Thermal screening does not predict failure.
Critical Infrastructure Scanned:
- Substation Transformers & Bushings
- Transmission Line Splices & Insulators
- Capacitor Banks & Switchgear
- Distribution Line Phase Imbalances
Our Inspection Methodology
Safe Standoff Distance
We utilize specialized enterprise drone platforms with high-resolution radiometric thermal sensors and optical zoom. This allows us to inspect high-voltage switchyards from outside the arc-flash boundary without requiring facility shutdowns.
Delta-T Classification
We compare temperature differentials against similar components under the same load and use grading concepts from applicable NETA and NFPA 70B guidance. These screening priorities are not root-cause diagnoses, certification, or accreditation.
CMMS Ready Reporting
Deliverables include fully structured, geo-tagged anomaly reports with side-by-side RGB and Thermal imagery. Data is instantly exportable to your existing work-order management systems for immediate lineman dispatch.
