How do you connect the capacitors on polyphase circuits?

Answer

In low voltage system we put capacitor bank in parallel to the PCC (POWER CONTROL CENTER) in that bank capacitors having delta connection.On HT bus series capacitor bank is used.Induction motor having long cable distance we use capacitor bank in delta connection.In large high voltage motor having large rating use capacitors bank along with reactor.
