how we can calculate which capacity capacitor bank we have
to add for improve pf?
Answer Posted / z_hosen
More simply,
Let total power is 1500kw
assume
cos 1 =power factor before improvement =0.75
cos 2= poer factor after improvement =0.98
tan1=0.88
tan2=0.2
and
kvar 1= power*tan1=1500*0.88=1320kvar
kvar 2=power*tan2=1500*0.2=300kvar
now, required rating of capacitor bank =kvar1-kvar2
=1320-300
=1020kvar =1000kvar

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
