Distribution systems traditionally did not involve much automation until the last quarter of the 20 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> century. The equipment installed on feeders was expected to function autonomously, with occasional manual setting changes. This was later referred to as `local intelligence' when other types of automation began to be developed. Recently, more stringent to improve reliability and efficiency of the power system and more automation has been introduced to distribution systems. In this paper, a general overview of structuring good criteria for switch location is going to be discussed. First, the definition of the optimal topology will be explained. Then, the criteria to define the right location of switches and its advantages on the distribution system is going to be discussed.
