A radial distribution system consists of 33/11 kV substation, 11 kV circuit breaker, 11 kV feeder, 11 /0.4 kVdistribution transformer, 0.4 kV distributor, service wires and load points. The reliability of distribution system hassignificant effect on the reliability of overall power system network. The reliability of 33/11 kV substation depends on thereliability of its components like power transformers, circuit breakers , bus bars and also operating weather conditions.The reliability of radial feeder depends on reliability of its components like distribution transformer, fuses,disconnectors, operating conditions of distributor like its length and voltage levels. In this paper the reliability ofsubstation is calculated assuming either all the faults occur in normal weather or in adverse weather. Thelow voltageradial feeder is converted into high voltage feeder and their reliability performance is evaluated. Further, the reliabilityof the complete distribution system is evaluated for all the above said conditions.
