Abstract :
The authors report on a high-voltage, frequency-domain measurement system capable of resolving losses in unaged XLPE (cross-linked polyethylene). The system allows analyses of harmonics as well as of the fundamental frequency. The highest operating voltage is 20 kV and the frequency range is 0.0001 Hz to 1000 Hz. Different XLPE cable samples (new, artificially aged, field aged) were measured in the frequency domain using 4 kV peak voltage at a temperature of 22/spl deg/C.
