As we all are familiar that equivalent capacitance of a delta bank is more than the equivalent capacitance of a series capacitor bank and so
more the capacitance = more the reactive power it supply
&
since capacitor bank's mere purpose is to supply reactive
power, delta connection will serve better.
it wld be more clear with expression:-
In delta, phase current=line current/1.732
capacitance required in parallel is 1/3 of capacitance
required in series
The effective capacitive
reactance is 3 times more when connected in parallel than in
series. So, to improve the p.f.
