Capacitor and filter bank protection
Shunt capacitor banks, also called filter banks, are widely used in transmission and distribution networks to produce reactive power support. ABB''s capacitor bank protection is used to protect against faults that are due to imposed external or internal conditions in the shunt capacitor banks.
