Answer Posted / syed masood
t he cable size depends upon the ams rating but the cables size defined standard value the ams rating enclosed this values some values 2.5,4,6,10,......630
first you have to know full conductor size standard value
then you calculate cable size depends upon the ams by using this relation cu=2-5ams per sq.mm
al=1.2-2ams per sq.mm
4 guage for 125-150ams convert guage into mm

I am abt to give IOCL intrv.Plz sir guide me for IOCL intrvw (Electrical).Which subject to be consider. questions are generally asked from which subject.Plz help me out.
A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
