In AC transmission line if conductor Diameter increase then
Skin effect increase due to high concentration of current
near outer surface of the conductor & due to this cause
Corona loss also increase.SO we use bundle conductors
instead of single conductor.
BUNDLE CONDUCTOR -When we combine number of conductors as a
conductor whose Diameter is small is called Bundle conductor.

CORONA LOSS-Hissing noise & luminous glow due to high
voltage ionises nearby air which cause power loss and also
effect communication signals.

what is the transmission loss for electrical supply? specifically a large shopping complex where the grid is half KM away, what will the % of transmission loss? is there any transmission loss for captive unit generation for above set? thanks
