what is the difference between earth and neutral?
Answer Posted / laiju j nair
it s a frequently asking interview question..
earth is defined as the protective circuit .
and neutral s defined as the current returning circuit.
in home,
ground wires are connected to all electrical equipments
metal body. if there s any fault in equipment , it may
cause current on its body. earth wire connected to metal
body carries this fault current to earth and decreasing the
effect of shock. for this , the earthing should be perfect.
AC is sine wave, ie voltages become zero in each cycles.
this zero voltage is referred as neutral. in 3 phase
transmission system, the voltage disbalance between lines
may leads to flow some current through neutral. due to this
reason neutral s earthed in all substations.. thank u..
