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.
The purpose of the protection scheme is to limit the effect of overload to a safe and acceptable level, and to prevent the abnormal system conditions from damaging the shunt capacitor bank by disconnecting it in case of a loss-of supply condition. Scope Product benefits
External power system conditions, such as overload, cause stress to capacitor banks. For example, overvoltage caused from the combined effect of sustained overvoltage and increased levels of harmonics create an overload situation.
