We have 2 Nos. Transformer with the capacity of 2000KVA and
1250 KVA and currently using only one 2000KVA T/R during
operational hours while non- operational hous 1250 KVA T/R
also used to reduce T & D losses. Similarly, 2 capacitor
bank of 500KVAR and 300 KVAR also installed to balance
reactive power. Now problem is around 1000 KW load PF is
not maintaning 0.99 as 350 KVAR capacitor is in healty
condtion. Now the PF is maintain 0.95 to 0.96.

Answer / arvind
You please check out the location of the capacitor banks
means whether it is away from the load or not if it is away
from tha load then power losses will be there and affects
the power factor.
secondly, if the load (1000kw) is variable means motor,
then it is difficult to get power factor 0.99.

Answer / muhammad azeem butt
we know that transformer is a inductive device it also
effect on our pwer factor lagging.
Power and distribution transformers, which work on the
principle of electron-magnetic
induction, consume reactive power for their own needs even
when its secondary is not
connected to any load. The power factor will be very low
under such a situation.
To improve the power factor it is required to connect a
fixed capacitor or a capacitor
Sl.no kVA rating of the transformer kVAr required for
compensation
1 upto and including 315 kVA 5% of kVA rating
2 315 kVA - 1000 kVA 6% of kVA rating
3 Above 1000 kVA 8% of kVA rating
