The Critical Angle of Ultrasonic Electrical Inspection of Transmission Lines and Enclosed Systems
Ultrasound is a powerful tool for detecting anomalies in energized systems, but its effectiveness hinges on one crucial factor: the Critical Angle—the precise position where sound waves reveal the truest signature of a fault.
This whitepaper explores how inspectors can optimize their approach to ultrasound testing, ensuring accurate diagnoses of issues like treeing, tracking, and partial discharge in transmission lines, switchgear, and enclosed systems. Learn how IR windows and ultrasound ports improve safety and efficiency by enabling non-invasive inspections, and why achieving the Critical Angle is essential for precision diagnostics.
With real-world examples and advanced analysis techniques, this paper is a must-read for professionals seeking to enhance their predictive maintenance programs.
