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

3. The Effect of Crosslinking on Morphology and Electrical Properties in LDPE Intended for Power Cables
Abstract : Crosslinked polyethylene (XLPE) is used as underground cable insulation due to its outstanding electrical properties and high temperature dimension stability. XLPE is often made by peroxide initiated crosslinking of low density polyethylene (LDPE). The introduction of unsaturations, i.e. READ MORE

4. Characterising Resistance to Electrical Treeing in New XLPE-Based Materials for High-Voltage Cables
Abstract : This work looks into electrical treeing in cross-linked polyethylene-based materials (XLPE), where the ability to resist tree development is considered as an indicator of improved applicability for insulation in high voltage power cables. The thesis presents results of a twin PhD project involving joint work of two students. READ MORE

5. High frequency characteristics of medium voltage XLPE power cables
Abstract : The response of a cable can be used to analyze the variation of the material characteristics along its length. For diagnosis of possible ageing, it is necessary to know how cable design, material properties and cable insulation ageing affects the wave propagation. READ MORE
