Diagnostics of high-voltage varistor quality using resonant ultrasound spectroscopy

Abstract

Resonant spectroscopy is an effective nondestructive testing method focused on defects detection in tested objects. Resonance spectrum contains an information about the mechanical properties and particularly about the structural homogeneity of the whole object. A swept frequency method has been used to measure the selected resonant frequencies range. The system for measurement of resonant ultrasound spectroscopy of high-voltage varistors has been described. At the output of receiving sensor resonances depending directly on the degree of inhomogeneity and dimensions of the object have been observed. The parameter Q related to the homogeneity of the varistor structure has been proposed as a criterion of testing.
