Abstract :
The diagnostic method for medium voltage cables based on the method of discharge current is an integral measurement technique, which means that the dielectric properties of an insulating material can only be measured in general, singular vacancies cannot be detected. The non-linear correlation between charging voltage and discharge current is a criterion for the state of ageing of the insulating material and gives information about its condition
