Why we use Capacitor in Single
Phase Induction Motor?

Answer Posted / meenakshi

there vil b two windings. they are main winding n starter
winding of two different inductances.i.e, one with low
inductance n another with higher value. so ther vil be a
phase shift of q1 and q2(say some angle)in accordance with
inductance value. NOW, IN ORDER TO INCREASE THE PHASE
DIFFERENCE BETWEEN Q1 N Q2, WE EMPLOY A CAPACITOR OER
HERE,WHICH MAINLY HELPS IN STARTING.

Is This Answer Correct ?    15 Yes 2 No

If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
