How the section of a transmission line can be used as lumped circuit element?
Actually in networks we will consider the elements like resistance, inductance, capacitance as lumped elements for simplicity, like this in power systems we will consider the transmission line parameters(resistance, inductance, capacitance) as lumped elements, because we will calculate all the parameters of power systems with respect to receiving end or sending end but not with respect to middle of the line. If a fault occurs on transmission line then we should not consider the lumped elements of that total transmission line, we should consider the lumped elements from sending end to the point where the fault is occurred.
What are the reasons that low frequency parameters cannot be Measured in microwaves?
(a) voltage and current readings vary with position along the transmission line, (b) voltage and current are difficult to define in non-TEM transmission lines.
Will low pass filter works as transmission line?
No, but transmission line act as a lpf
How to calculate the the number of insulators used in a transmission line?
The glass, 'dish', ('cap and pin') insulators used to support conductors from transmission towers are each rated to withstand a specific voltage. But this voltage depends upon the standards used by the electricity industry of the country in which you live but, typically, they are each designed for operating voltages within the range 10 - 12 kV. By dividing the effective line-to-earth value of the transmission voltage, by this value, you will be able to determine the the 'basic' number of dishes required. This figure, however, will only be a guide, as the voltage gradient across the string of insulators is not linear. Furthermore, additional dishes are sometimes required according to the environmental conditions affecting the transmission line. For example, if the line is near the coast, the dishes might be subject to salt deposits; if the transmission line is near industrial factories (e.g. steel works) then the line might be subject to deposits from airborne waste from those factories, etc. So, often, the number of dishes will be greater than that number required to provide the basic insulation level.
Who uses pole and transmission line hardware?
Pole and transmission line hardware is purchased by cable television and utility companies
What is the voltage regulation of medium transmission line?
Voltage regulation is just the percentage change in voltage at the receiving/sending end of the transmission line from no load to full load. It is given by ((Vnl-Vfl)/(Vnl)) X 100%. Typically Voltage at receiving end is known to us and for the sending end Vnl is given by Vs/A. Where A is given by the ABCD parameters of the transmission line and Vs = AVr + BIr.

What shape is generated when rectangle ABCD is rotated around the horizontal line through D and A?
Cylinder
Why higher voltege required for long transmission line?
To (a) eliminate high voltage drops along the line, (b) to allow conductors of practical size to be used, and (c) to reduce line losses.
Why are transmission lines less than 80km considered short?
The transmission lines which have length less than 80 km are generally referred as short transmission lines. For short length, the shunt capacitance of this type of line is neglected and other parameters like electrical resistance and inductor of these short lines are lumped.
What are the reasons that low frequency parameters cannot be Measured in microwaves?
(a) voltage and current readings vary with position along the transmission line, (b) voltage and current are difficult to define in non-TEM transmission lines.
How do you change transmission line?

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
Which sentence describes a poems meter a. the poen follows an abcd abcd rhyme scheme b. every three syllables in each line is accented c. the thunderstorm represents conflict?
14 syllables in each line is the correct one (apex)just took the quiz^
What are the components used for trnsmission lines?
There are no component is used in transmission line . the used things are- conductors for transmitting power to one place to another place. insulator for separate these conductors and some other basic things are required necessary for net of transmission line.
How do you find the equation of a line by the slope?
An equation of a line requires two parameters. The slope, by itself, is not enough.
Do you get DC current directly from the transmission line?
Only if it is a DC transmission line.
