I also faced this Question!!     Answer Posted By  
# 1
in balanced condition no current flow through neutral but
in unbalanced condition current flows thru it
Is This Answer Correct ?    71 Yes 4 No
# 2
In 3 phase with neutral wire system, if the loads on all
phases are equal, there will not be any current flow in
But if the loads on any phase/s are not equal compared to
others, there will be some current flow through neutral.
Is This Answer Correct ?    36 Yes 3 No
# 3
Current will only flow in neutral when there is unbalanced
load otherwise in balance load no current will flow in
Is This Answer Correct ?    14 Yes 2 No

The current will flow in neutral when circuit have in
unbalanced condition in three phase system.The magnitude of
current & impedance valeu is not same then retern current
flow in neutral wire for circuit comleted.
The single phase system neutral is required for circuit
complete.when circuit comleting then current flow by
neutral wire.
Is This Answer Correct ?    6 Yes 2 No

under unbalance condition of phase current will be flow
through the neutral .otherwise it will be remain zero..

In Y- connected load (3 phase)
1) If Ir= Iy=Ib then In=0 (Symetrical /balance)
2) If Ir#Iy#Ib ; then In=x (Unsymetrical/unbalanced)
where; Ir,Iy,Ib &In are phase &Neutral current
respectivelyand also #is is not equal

3)but in case of Single phase looping the avilability of
current will be.

The current always flow from higher potential to lower potential i.e, from phase to neutral(In a single phase circuit).as we know the T/F sec is star connected i.e, neutral wire is grounded in the T/F placing point, so all the current flows from phase through load to neutral(The return current always flows through the neutral for closing the circuit path) hence we cant feel the shock even if we touch the neutral wire because neutral is at ground potential(i.e, current always flows through the low resistance path)

we are genralley used tansformers secondary side star if we
take the load that time any phase cut or unbalance its
possible that s why weare useing in mcc's in neutral ct
Is This Answer Correct ?    3 Yes 2 No
# 9
yes,,current is flow from neutral when load is unbalance in
3 phase.
Is This Answer Correct ?    0 Yes 0 No
# 10
question is current flow in neutral rit.
so we can start from single phase. there is phase and neutral wire and we are connecting this 2 wire across any load ok.
phase wire carries in coming current and neutral wire carrries outgoing current. but when we touch neutral wire we wont get any electrical shock dats why every one have confusion. the answer is current is always flow through low resistance path. neutral wire potential is always zero and it is connected to earth in substation. so while we touching the neutral wire current has 2 path. one is through our body to earth , second one is through neutral wire . our body has some resistance. so obvoiously current wont flow through the resistance path in this case.
Is This Answer Correct ?    0 Yes 0 No

I hv a question regarding power factor improvement just after transformer. I request you to reply me plzz. thank you sir. My friend has a small unit of fabrication. in his factory the main load is a welding machine, lathe machine, grinding machine. this load is not continuous type. now our electricity board has installed 16 KVA, 11000/433 V transformer for our factory. In the energy meter (trivector meter) at LV side of transformer, i hv seen power factor value of 0.15 only when only 3 KW load was flowing. Further electricity board has suggested to install 4 KVAR capacitor at LV side after energy meter. Now my question is that if we permanantly install and switch on 4 KVAR capacitor after energy meter, during some load on transformer and also without any load on transformer, wht will be the power factor shown in energy meter?i dont want to get any penalty by electricity board, so plz suggest me if i can permanantly install and switch on the 4 kvar capacitor or not at LV side of transformer just after energy meter? Thank you again and awaiting for ur positive reply soon.   8
