E-Learning & Certification of electric substation design: electrical substation is a substation that, during the production, transmission or distribution of electrical energy, converts the voltage by means of a transformer to Changes higher or lower values. Electric power can pass through a large number of substations between the power plant and the consumer (charger) and its voltage can change many times along the way. Substations that use step-up transformers increase the voltage and thus decrease the current. While the substations that use step-down transformers reduce the voltage and increase the current. High voltage substations along with power transmission lines are the most basic components of the power transmission system from the producer (power plants) to the industrial, commercial and finally citizens. Electric substations are located at the place of production (power plants), the place of receiving energy (side of subscribers) and the place of intersection and connection of transmission lines, and by converting the voltage, they provide the possibility of low loss transmission of electric energy. Therefore, their role in creating a safe national electricity network is necessary and important.

In addition to electric substations, transmission lines are another important part that, along with substations, form the electricity transmission and distribution system. Decisions regarding the number and types of electrical substations along with transmission lines are made according to some factors such as the amount of electricity consumed in the desired area, the pre-designed distribution system, regional development plans, and economic and geographical considerations. Therefore, the construction of electric substations requires planning, forecasting and high precision in different stages from decision making to implementation. On the other hand, the levels of planning to transfer electricity to consumers are also different. From the highest levels, such as the design of the country’s electricity grids, to the smallest part of it in the transmission network of urban and rural areas. Designers of electricity transmission and distribution systems should consider the needs of industrial and end-consumer customers in the design of super-distribution and distribution systems. and prepare a comprehensive plan with both short-term and long-term views. In case of an increase in the demand of the subscribers for electricity, it is possible to supply and equip the electricity transmission and distribution network.
