how to calculate the size of cable for 100 kva load,?can
somebody tell me with a formula
Answer Posted / abdulsubur
WE CAN GET FROM THIS REALTION
KVA=KW/KVAR
100*85=85KW
THEN FIND CURRNET FROM P=ROOT 3 VICOSPHI FORMULA THEN FIND
CURRENT AND THEN LENTH FROM THE MV=VD*1000/L*I

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?
