  2. 1. Time and Frequency Domain Measurement Methods for High Frequency Characterisation of Power Cables

    Author : Ruslan Papazyan; KTH; []
    Keywords : Attenuation measurement; XLPE insulation; Power cables;

    Abstract : Time Domain Reflectometry (TDR) has been used forlocalisation of transmission line discontinuities in variousapplications. One of the challenges when applying TDR on powercables is to obtain knowledge of the high frequencycharacteristics of both the degraded and the undegradedsections of the cable. READ MORE
