Ultrasound Inspection in Medium Voltage Distribution
• Ultrasound inspection of approximately 6000 km of overhead power lines.
• Ultrasound troubleshooting and inspection was possible in instances when visual and thermographic inspections were not.
• Decreased overall circuit faults by 30%.
• $4,338,790 estimated annual savings.
• One year ROI of 173:1
Airborne and structured-based (A&SB) ultrasound can be used to detect various electrical faults; including corona discharge, tracking, and arcing. The PowerBeam 300 parabolic accessory allows the technician to locate sources of ultrasound with pinpoint accuracy from distances up to 300 feet away. Additionally, the InCTRL platform and InCTRL mobile app can be used to record samples, store testing history, and communicate faults through a management chain. InCTRL's FFT spectral analysis feature can be used to diagnose recorded samples for electrical failures. For more information the PowerBeam 300 and InCTRL, see the related products below.
Power Transmission and Distribution
The UL101 Electrical Inspector and PowerBeam 300 are used together to inspect medium and high voltage power lines, switchgear, and transformers. Inspection focuses the detection of corona, which is a symptom of two types of failures including material degradation and indeterminant by other technologies. The UL101 Electrical Inspector is very affordable and very effective in all types of environments for these tasks.
