State the effects of low power factor on efficiency and voltage regulation of short transmission lines. 

1 Answer

Answer :

i) Effect of Low power factor on efficiency:-

When power factor of load reduces current drawn by transmission line increases so copper losses in transmission line increases, hence transmission efficiency reduces.

ii) Effect of Low power factor on voltage Regulation:-

When power factor of load reduces current through transmission line increases, so voltage drop in transmission line increases so regulation increases. (Become Poor)
