Answer / rachuri_sree

APFC panel should be connected to main incoming busbar i.e.
from where 160 kva load was fed. 60 kvar capacitors should
be devided into smaller capacities i.e you have to use
either 6x10 kvar or 4x 15kvar or 10x6kvar. I will consider
6x10 kvar. in APFC you have to programe each stage
capacity. here the value is 10 kavar. You have to take 6
no. of capcitor switching duty contactros and to be wired
as per the APFC. It also requires one CT signal and voltage
signal(any one of the three phases of main busbar). You can
program s/on and s/off time in APFC. and also you can
program target power factor. EPCOS apfc is the best
controller I have used.

Answer / yuvraj gaikwad

devide the 60kvar capacitor into 4 or 6 banks of 15kvar or
10 kvar.use apfc relay of 4/6 stage which wil automatically
switch the cap banks to achive the target power factor.
The apfc i suggest is SYCON apfc which has more features
and available in diffrent models with fifo as well as
intelligent switching.visit website www.syconindia.com
