Testing Using Acoustic Measurements TRIZ Cases

Machine-learned vibration baselines help detect abnormal conductor events despite noise, cutting false alarms and missed discharges.

Non-invasive electric, magnetic, vibration, and acoustic sensing estimates vacuum circuit breaker arc duration for wear and lifespan analysis.

Electrostatic scanning detects slits or holes in elevator traction belt insulation faster and more reliably than visual inspection.

A fluid-filled tubular probe carries arc-generated acoustic waves to a remote sensor, enabling detection and localization along long electrical cables.

Compressed sensing extracts signal sparsity to detect arcs, reducing calculation resources and avoiding false alarms from load perturbations.

Linearizing nonlinear positioning equations eliminates iterative convergence failures and reduces operation time for accurate partial discharge detection.

Multi-dimensional trigger conditions isolate partial discharge pulses from high-magnitude noise, enabling precise source location averaging.

Audio detector captures acoustic waves near conductors while processor analyzes fundamental and harmonic frequencies to identify discharge events.

Electroacoustic transducers detect partial discharge vibrations, replacing high-stress electrical testing to prevent operational failures.

Antennas and microphones capture electromagnetic and acoustic waves from partial discharges, enabling precise localization of electrical component flaws.

A broadband ultrasonic microphone system measures airborne acoustic signals from electrical faults using a dynamic detection mechanism.
