For a renowned housing scheme, electricity provision is one the important task that is to be completed. Being a planning engineer you are required to assess the load for housing vicinity and provide reliable and affordable power distribution system. The society consists of hundred 120 sq.yards houses and it is not allowed to build other than ground floor due to aviation authority restriction. In first phase only 40 houses will be constructed so main task is to provide electricity. Suggest a distribution system along with the best suitable place for substation( keeping the fact that society is square in shape). The load assessment is to be performed using assumption of Load= 1.8/area of plot . Select a suitable size of power cable from nearest substation to society substation which is 2.05 km away. The ambient temperature is 95 degree Fahrenheit and cable is to be laid under 2 m depth. The core is made up of copper and cable insulation is of XLPE. The operating voltage is 0.4 kV at 80% power factor. Use Pakistan low voltage cable table for correction factors as cable is buried under a conduit system. Assume relevant data if necessary.
