Easy determination of insulation’s condition

DIRANA uses dielectric frequency response (DFR) analysis in order to determine the condition of high-voltage insulation systems such as those in power transformers, bushings, cables and generators.

It automatically analyses and determines the water content and the oil conductivity in different types of cellulose insulation. You can test assets filled with mineral oil, natural and synthetic ester as well as air or vacuum. The measurement results are shown in categories defined by IEC 60422.
