In the design of power distribution networks, mechanical and electrical calculations are important, but the lack of comprehensive software in this area and sometimes the time-consuming availability of easy access to them,led us easy-to-use.In this regard, the software is designed to carry out calculations of the transformer capacity, calculate active & reactive power and the cross section of the ground cable according to the permitted flow and voltage drop,meter to kilogram converter and perform calculations to determine the suffering of the cubic and capacitive banks. In each section, the required information and applicable tables are accessible from valid and verifiable references
