Document Summary

Transmission system consists of transmission line and substations. Two types of transmission lines: overhead lines and buried cables: overhead transmission line. Consist of three conductors suspended by towers or poles. Nevertheless, they are increasingly popular in new urban areas where overhead transmission lines are considered an eyesore. Substation is a subsidiary station of power system where voltage is transformed from high to low or low to high using transformers. Enable power exchange and increase in stability of the overall network. Distribute power to consumers by means of lower voltage networks. The medium voltage distribution is at 33kv and below i. e. 11kv, 6. 6kv or. The final consumer utilizes 415v three phase and 240v single phase. Grid system is an overall network that consists of many interconnected power system. Stability will increase with an increase in number of stations. : service continuity.
