How Power Intelligence deployed Hybrid Electronic Security and Condition Analysis technology to protect North Carolina Coop substation
On October 5th, 2023, the ScanIR Thermal Analytics system by Power Intelligence was successfully deployed at the JOEMC Morris Landing Substation in Holly Ridge, NC. This cutting-edge infrared pan, tilt & zoom sensor system now ensures continuous monitoring, measurement, and analysis of power delivery components and connections within the station.
ScanIR employs a specially designed continuously rotating high-resolution pan-tilt and zoom infrared camera, crafted by Planck Vision Systems. Embedded analytics establish a “nominal” baseline over time against which subsequent measurements are compared to assess the operating condition of the substation.
The Power Intelligence ScanIR system excels in measuring every device and bolted connection in the substation using a single sensor. This encompasses main and secondary disconnects, arrestors, transformer bushings and fans, circuit breakers, switches, reclosers, and voltage regulators—all achieved within minutes.
One notable feature of the new sensor platform is the exceptional accuracy and repeatability of the positioner, surpassing off-the-shelf positioners from other suppliers. Robin Thompson, CEO of Power Intelligence, highlights its significance, stating, “The device has far greater repeatability and precision of position, crucial for accurate measurements, especially over longer distances.”
“With the ScanIR PT, we can reliably repeat positions for measurements at ranges up to 100m within a few pixels every time. Combined with ScanIR’s built-in image registration technology, we can achieve nearly 100% position accuracy over hundreds or even thousands of operations.”
The comprehensive surveillance of the substation’s power delivery network involves continuous monitoring for changes in thermal conditions indicative of common faults. In a recent incident, the ScanIR system, installed just days prior, detected elevated temperatures in the B-phase of a secondary disconnect during a tropical storm. Thanks to timely detection, management was promptly notified, leading to corrective action that averted a potential outage.
Aaron Spencer, JOEMC VP of Engineering, emphasizes ScanIR’s value for operators facing staffing challenges, stating, “With ScanIR, we can achieve higher reliability and greater frequency than traditional manual inspections. The early success of this installation makes the case for greater automation for the benefit of our members and customers.”
To achieve this, ScanIR incorporates the patented Sigma Delta Tau measurement algorithm, enabling the identification of statistical outliers at distances up to 100m. This prompts the system to direct human resources for final evaluation and necessary mitigation measures.
