Description
The AQ-C255 capacitor bank protection devices have been specifically designed for the protection of capacitor banks. They include capacitor bank current unbalance, capacitor bank neutral unbalance, and overload protections in addition to the standard overcurrent, earth fault and voltage protections. AQ-C255 series offers a modular protection and control solution for applications that require a large I/O capacity. You can add up to 11 I/O or communication modules into the devices for extensive monitoring and control applications. The AQ-C255 capacitor bank protection devices communicate using various protocols, including the IEC 61850 substation communication standard.
We offer four (4) variants of the AQ-C255 feeder protection device: A, B, C, and D.
Highlights:
- Double busbar control.
- A large I/O capacity.
- Capacitor bank module with capacitor bank-specific protection functions.
- Current- and voltage-based protections.
- Cable-end differential protection.
- Low-impedance restricted earth fault protection.
- Harmonics protection and control.
- Power and energy measurement accuracy of up to 0.2 %.
- Up to 100 disturbance records.
