Answer / virendra

because the reactive prower produce by the Capcacitor may
harm the AVR of the DG set

Answer / kadiresan.k

whether the load is on EB or DG, p.f to be maintained close
to unity and the type of load to be studied and capacitor
to be connected accordingly. The Capacitors to be switched
ON and OFF according to the load with the help of APFC
panels / Controllers. In case of load shedding time, the
concerned capacitors to be tuned off immediately, else it
will result in over voltage at the system if the load is on
DG side. So the power system to be optimised to handle the
load in both EB and DG with proper power factor correction
systems.

Answer / william lobo

By putting capacitor on Genset what we are doing is only
loading the genset additionally.
Capacitor is used to improve the power factor of the
system. This is important for the power supply cos; hence
they insist that pf should be 0.9 or thereabout.
Hence it is compulsory to use Capacitors to improve the PF
if below 0.8 or they will fine you.
When using a gen set we have to see what is the type of
load. If it is motor load inductive then we have to switch
on some of the capacitor banks only.
