INTRODUCTION OF TRANSMISSION SYSTEM TRANSMISSION SYSTEM a transmission system refers to the infrastructure used to transmit electrical power from generating stations to substations and then to distribution networks. It consists of high-voltage power lines, TYPES OF TRANSMISSION LINE Overhead Transmission lines Subs transmission lines Underground Transmission lines OVERHEAD TRANSMISSION LINE An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles. SUB TRANSMISSION LINE Sub transmission lines carry voltages reduced from the major transmission line system. Typically, 34.5 kv to 69 kv, this power is sent to regional distribution substations. Sometimes the sub transmission voltage is tapped along the way for use in industrial or large UNDERGROUND TRANSMISSION LINE Underground transmission lines are electrical or telecommunications cables that are installed beneath the ground. Large natural gas pipelines are also called transmission lines, but the term underground transmission lines is normally used to distinguish HISTORY OF TRANSMISSION SYSTEM The first industrial electricity transmission line in Italy, between Tivoli and Rome, entered into operation in 1882: a 5,100 Volt single-phase electricity line, formed by metal supports made of double beams, concrete bases and insulators mounted on bolt hooks on  The foundation of modern electric power transmission was laid in 1882 when Thomas A. Edison's Pearl Street Station, a dc generator and radial line transmission system used primarily for lighting, was built in BENEFITS OF TRANSMISSION SYSTEM Reduce household Energy cost Lower energy bills Improve grid Reliability Reduce emissions IMPACT OF TRANSMISSION SYSTEM Long-term impacts can exist as long as the line is in place and include land use restrictions, loss of woodland, and aesthetic impacts. Temporary impacts occur during construction or at infrequent intervals such as during line repair or ROW maintenance. They can include noise or crop damage during ADVANTAGE AND DISADVANTAGE OF TRANSMISSION SYSTEM ADVANTAGE OF TRANSMISSION SYSTEM Low Transmission losses Better voltage stability Reduce costs Increased power Transmission efficiency Higher operating voltage DISADVANTAGE OF TRANSMISSION SYSTEM Transmission Losses Voltage Drops High Capital Costs Reliability Concerns SUMMARY OF TRANSMISSION SYSTEM The electrical transmission system constitutes the backbone of power distribution, transmitting electricity from power plants to consumers over extensive networks of transmission lines and substations. Operating at high voltages, it minimizes energy losses over long distances, though challenges such as voltage drops and electromagnetic interference persist. Despite its critical role, the transmission system faces hurdles like environmental impact, high capital costs, and reliability concerns. Technological advancements and smart grid initiatives aim to optimize efficiency, enhance reliability, and integrate renewable energy sources into the grid, reflecting ongoing efforts to adapt to evolving energy needs and promote sustainability in the electrical transmission landscape. THANK YOU AND GODBLESS EVERYONE
