grounding means eathing for protection of m/c & other elect. Equpment .neutral for make the close ckt path.

Answer / bishnu das

neutral is the return path of the current through which
the circuit get closed while earhing is the conneection of
euqipment to the earth to protect the equipment and the
users too.

Answer / j.karthik

Ground:
It doesnot give a zero reference point of the voltage
It doesnot maintain a voltage stability of the system
If any fault happens in the system means then the fault
current will passes to the ground terminal.

Neutral:
It gives a return path of current.
It maintains the voltage stability of the system.
It gives a zero reference point of the voltage.

NOTE:
In Practically the Neutral wire is connected to Earth
in the nearest substation.....

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
