why capacitor bank always connected in delta,why not in
star to a system?
Answer Posted / roysayan01
The reasons are-
1) The 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 will it supply
& since capacitor bank's sole purpose is to supply reactive
power, delta connection will serve better.
2) If there is any circulating current in the bank then in
delta this circulating current remains within the bank &
dont get spread to whole system unlike in star connection.
(for easy remembrance- due to the triangle shape of delta
connection circulating current circulates within the
triangle only)
3)In delta, phase current=line current/1.732
i.e the phase current becomes smaller and thus the losses
also decreases.
