Introduction Transmission Line
Capacitance.
www.sah786.wordpress.com

6.
• 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.

8.
Electric field
Electric field: Region around the electric charge in
which another charge experiences a force of attraction
or repletion

Bundle conductor
www.sah786.wordpress.com

15.
Many types of bundle conductor
www.sah786.wordpress.com

16.
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
