Answer / m raviteja
capacitor is static device which can store the energy in
the form of eletric field, Q=CV. We can switch on and off
the capacitor bank depends on the load. Normally capacitors
in the industries are dependent on power factor.
from power equation p=1.732vicosphi.

Answer / guest
normally the capacitors are switched on to bring the power factor nearer to unity i.e 1.
if load(kw)is almost equal to generator capacity (kva)or if power factor is between 0.9 to 1 we wont Switch on the capacitors.
capacitors are rated in kvar(kilo volt amp reactive )
apparent power=kvar=sqrt(3)*V*I*sin phi

after parallaing two generators current is shooting up in both the generators.for ex: load is 400 kw..after paralling and load sharing current in running gen is approx 900 amps and incoming is 750 amps which is too high when trying toshift the load current in incoming gen is coming more than 1300 amps and both getting tripped and making blackout..
