Answer / prashant

the cables used in transmission lines are of higher rating
as compared to communication line. if ever they were same
then the distortion in communication due to the harmonics
would also increase. henceforth for better communication and
better transmission these lines have different ratings.

Answer / gunasekaran

power rating is more in transmission line like KVA or MVA
communication line power rating in mVA

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.
