Abstract

Dielectric spectroscopy, a method for nondestructive material characterization, is now available for practical diagnostic measurements in the field. The method is, due to new technology, easy to use and shows significant advantages in the interpretation of the results, especially compared to simplified methods like measurement of dissipation factor at a fixed frequency. The method is briefly explained with application on polymer cables. Additionally, the application on paper insulated power cables is introduced
