The NEutral Wire is thinner than the phase wire because
netural has to carry the reactive compoment of the main
value back to the system.
All other components are being trapped and utilized by the
system.

Answer / simon

The word Neutral itself mean nothing i.e if u use a potentiometer then u will see the potential diff among both.

Answer / preethi

please sir can u explain once again clearly and another doubt
if any abnormal conditions in phases neutral grounded is essentially needed?

Answer / mohak gupta

Well in current components are present as active and reactive.
In case of normal phase condition all the components of current according to the phase are considered. But at neutral only the reactive component is being sent back as it is not being utilized by the system.
For second case well in case of faults in the phases all the short circuits occurs due to which neutral grounding is necessary so as to carry the fault currents and to protect the mail system operating machine.
Otherwise the SC currents will go to the machine and will damage the system.

Answer / badri narayan satpathy

Because the neutral wire takes negligible current then
phase wire.Due to the power being utilized by the system or
load.Neutral is the returning path to close the circuit.

In DC while we mention the voltage we are using -48V but in case of AC we mention only 230V not -230V, why we using -48V not 48V

In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
