The actual voltage drop is lesser than the permissible voltage drop -->

Check for Short circuit withstand capacity of the cable

 The conductor size is checked for short circuit with the following formulae: Isc =143 x S / √ t , where t = Duration of Short circuit = 1 S = Cross sectional area of the cable = 630 Substituting in the above equation, we get Isc = 90090 = 90 Rated fault withstanding current at the Tranformer = 80.325 Short circuit current withstand capacity of the cable is higher than that
