advantages:due to corona formation the sir surrounding the conductor becomes the conducting and hence virtual dimeter of the conductor is increased.

What is line charging in transmission?
Transmission Line Charging To initially charge the transmission line, the generator voltage stably controlled from 30% of the rated voltage to 110% of the rated voltage by using AVR. The change-over switch (43CH) for initial transmission line charging is mounted on the operator's desk in the main control room.This Voltage Changes are required because of the Stray capacitance effect at the charging and boosts the Voltage at the other end and the inductance of the line drops the Voltage soon after charging
Name the two basic types of transmission line which is most widely used?
coaxial cable and twisted pair cable. coaxial cable is the most widely used type of transmission line.
What is Serial line interface protocol?
It is a very simple protocol used for transmission of IP datagrams across a serial line.
What is the main limitation of microwave transmission?
The main limitations to Microwave transmission is the fact that it needs line of sight and that it can be subject to interference such as planes passing over, or rain
Why transmission lines are thicker than TV cable wires?
Transmission lines are thicker than TV cable wires because the transmission lines are used to transmit both low freq and high freq signals. And the losses of the transmission lines depend the resistance of the line which inturn depend upon length and area. As we have to transmitt the signals over long distances the transmission lines are thicker in size.Whereas in TV cable wires the construction is totally different in which transmission of signals is in between two conductors thereby avoiding losses.Therefore there is no necessity for these lines to be made thicker. That is why transmission lines are thicker than TV cable wires.
What is difference between advantage and disadvantage AC and DC power transmission line?
The main advantage of ac- it required less maintainance The main disadvantage of ac-it can not be stored the main advantage of dc -it required less amount of conductors to transmit and easily stored The main disadvantage of dc-it is more dangerous than ac at high voltage
What are the Advantages of Corona in transmission lines?
Due to corona effect virtually conductor size is increase and therefor resistance in transmission line is decreases.so I2R losses will decreases...
What is corona power loss in transmission line hvdc?
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.
What is Corona power loss in transmission line?
Corona Fields arround a transmission line is the high electric field caused by the transmission line causing the surrounding air to ionise and conduct electricity. As this ionisation requires a current to maintain, this causes a loss associated with the corona.
Advantages and disadvantages of line printers?
I know they are fast at printing (advantage) and they only print in black (disadvantage)
What is a major advantage of having a compensated transmission line?
The advantage of having a series compensated line is that it corrects for undervoltages created when a line is overloaded and acts as an inductive element. To compensate for this a series capacitor is added to produce the extra Vars being absorbed by the overloaded line. This will create a smoother voltage profile across the transmission line.
Describe the various methods of reducing corona effect in an overhead transmission line?
1. by increasing conductor size. 2. by increasing conductor spacing.
Why more humming noise in HT electric line?
corona effect
How do you change transmission line?
how to fix a transmission without taking it a part how to fix a transmission line
What is the disadvantage of in-line engine configuration?
i dont no
What is the disadvantage of strip line over micro strip line?
more radiate.
Do you get DC current directly from the transmission line?
Only if it is a DC transmission line.
