Que: Is it true that in India electrical power is transmitted from 3
phase, Star (Y)- Neutral
configured secondary of some power transformer AND any Phase to
Star neutral forms
the configuration for Single phase-Neutral (P-N) power we
receive in our homes?
If YES, then
(I) Phase is positive with respect to the Neutral during
positive half cycle of sine wave.
(II) Neutral is positive with respect to the Phase during the
negative half cycle of the sine
wave. IF THIS NEUTRAL IS EARTHED, THEN HOW DOES THIS POWER
THROUGH THE ELECTRICAL LOAD? It flows through the Earth
connection as this has
lower impedance than the load, isn'it?
