Description
The AQ-F255 feeder protection devices offer a modular feeder 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 device for extensive monitoring and control applications. The AQ-F255 feeder protection device communicates using various protocols, including the IEC 61850 substation communication standard.
We offer four (4) variants of the AQ-F255 feeder protection device: A, R, S, and V.
Highlights:
- Double busbar control.
- A large I/O capacity.
- Current-based and voltage-based protections.
- Cable-end differential protection.
- Low-impedance restricted earth fault protection.
- Harmonics protection and control.
- A 5-shot scheme-controlled auto-recloser.
- Power and energy measurement accuracy of up to 0.2 %.
