Answer / ravi

If the supply source in star connection and the obtained
neutral is not grounded then in case of the unbalnced load
neutral point will shift causing unequal phase voltages.

Answer / sorabh

if the unbalance load exist in the system in that case some voltage is developed at the neutral point beacuse the current at the neutral point is zero( in case of 3-phase system) if neutral is not earthed, the magnitude of the voltage developed at the neutral depend upon the unbalance load it might be produced in order of KV

Answer / sunil bhat abb

Floating Neutral is a condition when neutral is not
grounded the case may be when single phase Cable say 66 KV
having lead sheath is not grounded at either side as a
consequence the Neutal end point (sheath ) develops some
potentail say 50 Volts under normal condition and in case
of fault due to transformer effct between sheath and
conductor the voltage of unearthed(floating end) end gets
abnormally high so a Lighting arrestor /surge arrestor is
used at floating end

Answer / sanjay kumar singh medicity h

it means there is neutral disconnected from earth or u can
say isolate like Medical isolation transformer .

Answer / ayyappss

A floating neutral has no direct connection to ground and
is generally used for in house motor operators or control
or in house lighting.

Answer / girish kumar samal, hindalco,h

it means there is some unbalance load &current flowing in
nutral

Answer / satish

neutral conductors whose voltage to ground is free to vary
when ckt condition changes

Answer / shaik dawood

I Thing this type of floating neutral system used in
aeropline,Further Neutral of the Flight wire will be
connect with flight body. Because There is no return path
to this current.It means the Return path current will be
neutralized with air atmosphere.(Dear Friends If its wrong
plz clarify dawood_ee@yahoo.co.in)

Answer / sudhakar

The floating of neutral is called unbalanced in neutral
system

in power generator normaly voltagr betwween esth to neutral is 0 but my work place generator show the volatge is 60v any body know why? thanks
