The AQ-C255 capacitor bank protection device has been specifically designed for the protection of capacitor banks. It includes capacitor bank current unbalance, capacitor bank neutral unbalance, and overload protections in addition to the standard overcurrent, earth fault and voltage protections. AQ-C255 offers a modular protection and control solution for applications that require a large I/O capacity. You can add up to eleven (11) I/O or communication cards into the device for extensive monitoring and control applications. The AQ-C255 capacitor bank protection device communicates using various protocols, including the IEC 61850 substation communication standard.
