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.
