A sensitivity approach to the sizing of insulated power cables in low and medium voltage electrical power distribution systems

The author develops cable-sizing criteria using sensitivity techniques. High-sensitivity parameters that influence cable size can be determined in each voltage class and design criteria formulated, to apply to both AC and DC systems. Copper and aluminium conductors with thermosetting (ethylene-propylene rubber or cross-linked polyethylene) or thermoplastic insulation are compared for use in the above systems with regard to their electrical characteristics only. Cable-sizing criteria are considered for a typical power system at both low voltage and medium voltage
