|what is the disadvantage of leading power factor...why can't
we use it (pf=0) for a long period of time?
|what is difference between 3.5 core and 4 core cable
|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.
