• 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

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
