The Low Voltage (LV) grid, particularly in urban areas of many modernized countries, is exclusively based on connections with underground power cables. Loading usually is far below their ampacity and so far, no major concerns have been raised on the condition of the LV grid. Repeated failure is the only cause for replacement. However, historical failure rates of LV cables indicate that flawless operation cannot be taken for granted. Furthermore, with the increasing penetration of de-centralized generation, an increased pressure is expected on the performance of the LV infrastructure. No methods are currently available to effectively assess cable life expectancy. This calls for an investigation into options for condition monitoring of the LV grid.
