In the field of engineering design of power distribution networks, the urgent need for conventional mechanical and electrical calculations is inevitable, but the lack of comprehensive and efficient software in this area and the scattering of resources and sometimes time-consuming easy access to them made us soft Provide practical and easy-to-use software with the required database in this field. In this regard, computational software has been designed to perform active and reactive power calculations, transformer capacity calculations, accurate ground cable cross-sectional calculations based on allowable voltage drop current, wire weight to its length and vice versa - perform CT range calculation calculations and Capacitive bank - mechanical calculations of power distribution including calculation of flash and traction and base power. Also, in each section, the required information and application tables are available from valid and approved authorities
