Transmission Lines Flashcards
When alternating current passes through a conductor…
portion of the conductor near the surface carries more current as compared to the core.
The skin effect of a conductor will reduce as the…
resistivity of the conductor material increases.
The effect of the corona effect is.
An increase in energy loss.
Corona effect can be detected by:
Hissing sound, faint luminous flow of bluish color, and
presence of ozone detected by odor
The presence of ozone as a result of corona is harmful because…
it corrodes the material.
The effect of ice on conductor is…
increased weight.
ACSR conductor implies
Aluminum conductor steel reinforced
Bundling of conductors is done primarily to…
reduce reactance.
The function of ACSR conductor is to…
provide additional mechanical strength
String efficiency of an insulator is given by
(voltage across the string)/((number of discs on the string) x (voltage across disc nearest to the conductor))
