Answer / sudipto jena

Hello friendz, this is sudipto,from rourkela
skin effect is the tendency of AC current that it is
distributed in such a way that the current density is largest
at surface of the conductor and decreases towards core.
Now u can answer ,why conductors comes in strands in stead of
single wire.

Answer / dorji

If i answer to no.1
Conductors comes in strands coz, larger cross section of conductors can be used & on other hand if we happen to use single wire then, as said above the density of current will be high at the surface(skin effect), it means it uses only outer part of the conductor and no full utilization of conductor.

Grounding. Dear all at one of my site we checked the amps at the earthing cable to the alternator it was found 125 to 130 A. at the neutal cable in same machine found 146A. in the same plant checked the earthing current on other alternator it was 52A, and neutral 116 A. we are facing problems with our controller and the card was damaged once. can that neutral/GND current be a reason? as there is common grounding for the Alternator,Brkr panel,Transformer?
