Introduction Transmission Line Capacitance.


• The capacitance of a transmission line is the result of the potential differences between the conductors themselves as well as potential differences between the conductors and ground.


Coulomb's law

Coulomb's law: Like charge repel and unlike charge attracted each other.


Electric field

Electric field: Region around the electric charge in which another charge experiences a force of attraction or repletion


Potential different Difference Between Two Points.


Capacitance of single phase two wire line.


Capacitance of three phase line with Unsymmetrical Spacing.


Effect of earth on transmission line


Bundle conductor


Many types of bundle conductor


Advantages of bundle conductor

•Current capacity increased•Reduced corona losses•Improving skin effect•Reduced line inductance(improve p.f.)•Reduced Line heating•Reduced voltage drop of transmission line


Electrostatic induction
