Answer / janardhan

The tendency of current to flow through outer surface or
circumference of conductor is called "skin effect".

Answer / vikram pandiyan

if a conductor has a large dia ,then the curent flow will
be limited to the periphery of the cinductor .hence the
effective resistance of the wire is increaded .this will
cause heating and hot spots along the periphery of the
conductor and damage the comductor.

Answer / k naga muneendra reddy

when AC current is allowed to flow through a solid
conductor, distribution will not be uniform through out the
diameter. current density will be more at surface than at
the center. that's why all bus bars are made of hallow
conductors only not with solid. and also our EHV
transmission conductors are also twisted so that skin effect
is eliminated. not only EHV all electrical cables are also
having twisted conductors inside.

Answer / sunil guru

SKIN EFFECT--- IT IS THE UNEQUAL DISTRIBUTION OF CURRENT...IN THIS THE CURRENT FLOWS AT THE SURFACE OF THE CONDUCTOR RATHER THAN BULK.....SO CAUSES HEATING OF THE CONDUCTOR AND THUS THE LOSSES ARE INCREASED...

SKIN EFFECT MAINLY DEPENDS ON
1.SURFACE OF THE CONDUCTOR
2.MATERIALS USED IN THE CONDUCTOR
3.FREQUENCY

In over head lines..
The phinamina of hissing noise and
visible glow is called skin effect.

Answer / deepa

it is the tendency of an ac to distribute itself within a
conductor so that the current density near the surface of
the conductor is greater than at its core.ie)ac flows at
the skin of the conductor.it is due to eddy current setup
by the ac.

Answer / bharatkumar

Non uniform distribution of current in the conductor is
called SKIN EFFECT.

Answer / prasad

it is atype of skin diseas.

my 10 hp submersible pump is tripping when connected through ELCB.I have checked the megger value of the coil's with body.It was found to be 0.2mega ohm.that is leakage is there.But when connected to mccb it is not tripping.no leakage current in the motor.Is it safe to connect to mccb? what are the problem's will arise if future?also tell me in ELCB no neutral is connected to motor.than how ELCB was working?
