The shunt conductance is due to leakage currents flowing across insulators and air. As leakage current is considerably small compared to nominal current, it is usually neglected, and therefore, shunt conductance is normally not considered for
the transmission line modeling.

Distancebetween overhead power lines and houses?
20 feet.
What are the 4 primary constant and secondary constant of transmission lines?
resistance (R) inductance(L) capacitance(C) shunt conductance(G)
Why capacitance is neglected in short transmission lines?
Wen the length of overhead transmission line is less than 80 km with an operating voltage up to 20kv it is considered as short transmission lines Due to smaller lengths and low operating voltage the charging current is low so the effect of capacitance of short transmission lines is extremely small and therefore can be neglected as in case of distribution lines and only R L is to be taken into account while analyzing short transmission lines
What is the purpose of ground wires in overhead transmission lines?
connection of the ground of all the transmission lines and used as a communication cable between protection devices
Does duct tape conduct electricity?
Yes. It should not be used where there is any danger to electrical leakage. Definitely not on 110/220 VAC lines.
Why conductance is ignored in transmission lines?
Conductance is ignored in short circuit studies because the inductance of the line is the dominant value. Conductance may not be ignored in stability studies.
Where does electricity go after it goes to the wooden overhead lines?
Overhead distribution lines are made of aluminium not wood.
Distancebetween overhead power lines and houses?
20 feet.
How can oil leakage be prevented in the future?
Well by not allowing boats not near coast lines
What are the materials added in electrical overhead lines?
Overhead electrical lines are usually made of aluminum, and some have a steel strand added which is used to give the conductor more strength (not to carry current).
What are the 4 primary constant and secondary constant of transmission lines?
resistance (R) inductance(L) capacitance(C) shunt conductance(G)
Which of the above lines appear to be neither perpendicular nor parallel?
You may have neglected to copy something else that goes with the question, as there are no "above lines".
Are overhead power lines insulated?
Overhead power lines are insulated from ground, typically using strings of glass or ceramic insulators. The wire itself is bare, though - it does not have insulation on it. There are many different types of overhead power line, but I'm not aware of any that actually have insulation.
What are contour lines used for?
Contour lines enable us to see changes in elevation using an overhead map
Why overhead transmission lines would be more economical than underground transmission lines in high voltage transmission?
Overhead wires do not require insulation, and it is easier to plant poles than dig miles of trenches.
What are old powerlines along railrd tracks ,made of?
powerlines mounted on pylons, see Overhead power line. For lines carrying information, see Overhead cable. An overhead line or overhead wire is used to transmit electrical energy to trains, trolleybuses
What has the author Guido Semenza written?
Guido Semenza has written: 'Graphical determination of sags and stresses for overhead line construction' -- subject(s): Overhead electric lines
