By using network reconfiguration process many distribution system problems can be solved such as planning, energy restoration and loss minimization. This paper describes about loss reduction in a radial distribution system by doing network reconfiguration using new algorithm i.e. Gravitational Search Algorithm [GSA].GSA considers all the objectives in order to meet the reliability requirements. And because of this the processing time can be reduced also the quality of solution can be improved. The proposed approach has been applied to distribution test systems including IEEE 33 system.
