Investigation of Effects of Short-term Thermal Stress on PVC Insulated Low Voltage Distribution Cables

The main aim of this study is to investigate the ageing process Low Voltage cables in smart grid. In addition, behavior phenomenon has also been investigated. cable networks were developed decades ago and it utmost importance make comprehensive over health existing so as avoid any unprecedented damage. Incessantly increasing energy demand distributed generation makes among top priorities cables.The effect thermal stress dielectrics was investigated a part research. To be able determine these effects measurements done on PVC insulated (both cores jacket) by measuring tan? (dissipation factor), capacitance, return voltage hardness insulations. order dielectric, different temperature ranges i.e. at 110 °C, 125 °C 140 °C.The results support expectations. mechanical electrical parameters insulation are affected stress. dissipation factor increased while decay slope ( Sd ) decreased ageing.
