ULTRASONIC METHOD FOR TESTING OF POWER TRANSFORMERS

Journal of Energy : Energija, 2022
Ultrasonic method of detecting PD is based on the fact that the electrical energy of the PD transforms in a mechanical energy, an ultrasonic acoustic wave that spreads through the transformer to the tank wall. From time difference of wave detection on different sensors, a possible location of the source can be estimated.

Supershear Rayleigh wave imaging for quantitative assessment of biomechanical properties of brain using air-coupled optical coherence elastography

APL Bioengineering, 2023
Recently, supershear Rayleigh waves (SRWs) have been proposed to characterize the biomechanical properties of soft tissues. The SRWs propagate along the surface of the medium, unlike surface Rayleigh waves, SRWs propagate faster than bulk shear waves ...
