what is the difference between earth and neutral?
Answer Posted / akash soni
Neutral is the point at which all the three phases current
meets and the algebric sum of current becomes zero in case
of balanced load condition.
Neutral is usually grounded with some resistance in series
in case of equipment protections like generator and
transformer protections.
While earthing is the "dead zero point" in electrical
system. I.e zero potential point or reference potential.
