Answer / hari krishna maganti

we r not useing always 2 or 3 phase suply..
for singie phase suply neutral is must.....

Answer / mintuk1@gmail.com

For transmitting the power generating substation transformer should connect delta star for step up at high voltage also getting ground wire for reducing third harmonic current in transmission line.

Answer / bhramit agarwal

bcoz ie is in star per phase voltage is 1/3^1/2 times the line voltage.so overall voltage decreases.and loss in a line is decreased.

Answer / suresh apgenco

to provide path for third harmonic currents and as line
voltage is equal to phase voltage, size of the conductor
will reduce.

Answer / prateek negi

BCOZ STAR POINT GENERATES NEUTRAL AND ELECTRICITY IS
DIDTRIBUTED IN THAT FORM WITH 3 PHASE AND ONE NEUTRAL

The initial current is very large at the time of starting for almost all DC motors. SO WE USE STARTER FOR A SAFE STARTING but at our homes we don’t see any starters in our coolers, motors.WHY DON’T WE NEED STARTERS FOR THESE APPLIANCES?
