Due to corona effect virtually conductor size is increase and therefor resistance in transmission line is decreases.so I2R losses will decreases...
The virtual diameter of the conductor becomes greater to carry more current
A: Transmission lines while there is ceramic insulators providing separation to the phases will have a corona if the insulators are dirty providing small current leakage ionizing the air around it therefore corona effect.
Advantages of corona in power system
for sake of safety and protection the high voltage transmission lines are erected in less populated areas ie. villages , these lines have operating voltages about 220kv , 440kv , 132 kv( high tension lines) . while in cities the voltage is distributed at low voltages ( about 11kv(industry) , 440v residential ) because of safety issue . since corona loss highly depends on the operating voltage of lines thats why it is mostly seen in villages.
Because of the high value of traveling voltage in the TX lines theair around it actually ionizes and cause the current to flow in the surrounding and because of that ionization ozone gas is produced
You can disconnect the 1996 Jeep transmission lines with a 9/16 open end wrench. Be prepared for transmission fluid to come out of the transmission lines.
One reason is that since the electrons travel on the surface of the transmission lines there is more surface area when conductors are bundled thereby reducing resistance to current flow thereby reducing the voltage drop across the transmission path. In extra high voltage line an electrical discharge formed by ionization of fluids surrounded by the conductor which is highly energized , so energized that it creates electrical conduction but not high enough to electrical breaking or arcing surrounding objects. this phenomenon is called corona losses.to prevent this corona loss bundle conductor is used.
advantages:due to corona formation the sir surrounding the conductor becomes the conducting and hence virtual dimeter of the conductor is increased.
if you are asking about the cooling lines for the transmission that connect to the radiator, its easy. first disconnect the lines from the radiator (2 lines, usually on the bottom opposite the radiator outlet) then disconnect the lines from the transmission. remove the brackets holding them on, then remove.
yes, i think dc transmission is best, coz in dc losses is low, no iductance between conduct, less corona loss.AnswerNeither is 'better'; they each have advantages and disadvantages. For example, although there might be less losses with d.c. transmission, the equipment required to raise and reduce the voltage at each end of the line is more costly than for an a.c. transmission system.
The major material used in the construction of transmission lines is aluminum alloy. Steel is also used to reinforce the lines. No insulation is used for overhead transmission lines.
In the transmission lines, there is no apparent change in the condition of air(CORONA) surounding the wires if the applied voltage is low.However,when the applied voltage exceeds the certain value,called disruptive voltage !!!
