What is Long Transmission line?
Long Transmission Line Lines having length more than 200 km are called long transmission line. As the line constants of the transmission line are uniformly […]

Primary Distribution system Primary distribution operates at the high voltage such as (3.3,6.6 and 11 KV).Primary distribution is usually carried out by 3-phase,3-wire system.Electric power […]
Comparison between DC and AC system for transmission and distribution Transmission of electric power by high voltage dc system is superior to that by high […]
Substation Introduction Substation receives the energy transmitted at high voltage from the generating stations and reduces the voltage to a value appropriate for local distribution […]
Three-Wire DC Distribution System When the voltage is increased the efficiency of the transmission line increases and the cost of conductor material in feeder cables […]
Skin Effect The distribution of current over the cross section of the conductor is uniform for dc only.An alternating current flowing through a conductor does […]
Bundled conductors Transmission of large amounts of power over long distances,can be accomplished most economically by using extra high voltage(EHV).An increase in transmission voltage results […]
what is Transposition of lines? Transmission line transmits bulk power at relatively higher voltages.These lines gives rises to electromagnetic and electrostatic fields of sufficient magnitudes […]
Medium transmission line Transmission line having length between 80 Km and 200 Km and line voltage between 20 KV and 100 KV fall under medium […]
Short transmission line Transmission line having the length lesser than 80KMĀ and operating voltage lower than 20 KV falls under short transmission line.The capacitance effects […]
