What are formula we can apply to determine the HT/LT current of 11KV/433V transformer except KVA/LV×√3. ?

Answer Posted / haider

P=Root3 *VIcos$
P=KVA rating of DTR
V=primary volage (HV side)
cos$=power factor
Exp:
100KVA DTR
primary volage =11000V
let Power factor=0.97
I=kva/1.732*11000*0.97
I=5A

Is This Answer Correct ?    12 Yes 18 No
