000000165 520__ $$aThe paper presents non-destructive ultrasonic method for investigations of long-rod insulators, operated on overhead power lines and stations. It was established correlation between the degree of C 120 porcelain material degradation and the parameters of ultrasonic wave propagation and attenuation. As example of application of the method there were presented ultrasonic examinations of two groups of insulators – 15 line and 49 station post. On the basis of the measurements advancement of ageing degradation of the material and the quality of the tested insulators were ascertained.
