Abstract

In this work the relations between the time and frequency domain parameters of the dielectric spectroscopy will be discussed. Then the results of dielectric response measurements in time and frequency domain on the insulation systems which are used for high voltage rotating machines will be reported. As test object, actual stator bars were used based on the epoxy VPI technology. The linearity of the insulation system will be checked and the possibility to transfer the measuring data from one domain to another investigated. The paper compares the calculated and measured data and shows the influence of difference parameter.
