Arcteq AQ-F255 - Feeder Protection Relay.

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.

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 %.
