Taking the composite insulator as a measurement sample, knowing the waveform conversion condition on the boundary, only a conventional longitudinaltesting probe is needed to measure...
This paper deduces the errors sources from the process of ultrasonic longitudinal wave testing and evaluates its uncertainty.
