Learn MoreCapacitor Bank in 33/11Kv Substation . A capacitor bank is used to improve power factor in a 33/11kv substation. It does this by storing energy in the form of an electric field, which can then be released back into the system to help offset inductive loads. This results in a more efficient use of power and can help to lower overall energy costs.
