In this fast growing world, automating a distributing system is an effective means of providing a reliable system. There is an increasing interest in the quantitative assessment of power system reliability worth and its application to cost-benefit evaluation in power system planning. Hence this paper deals with automating a system using two stage restorations (partial automation). It introduces a feeder automation system using the concept of optimal placement of switches that can be applied to electrical distribution systems for high economic-technical efficiency. Reliability is analyzed and evaluated when feeder automation is applied to distribution and its worth is assessed. This paper, further, looks into a case study involving reliability and economic evaluation of Urban, Rural and Industrial Feeders and draws a most probable conclusion.
