Description
The AQ-F255 Line Protection Devices offer a modular solution for line protection and control applications that require large I/O capacity. They can also features both distance protection and line differential protection for two line terminal ends. You can add up to 11 option modules (I/O and other type of modules) into the device for extensive monitoring and control applications. The AQ-F255 Line Protection Devices support a large variety of communication protocols, including communication according to the IEC 61850 standard.
We offer four (4) function packages for the AQ-F255 Line and Feeder Protection Device: B, C, D, and E. See below for their individual differences.
- AQ-F255B – line differential + current protection
- AQ-F255C – line differential protection + full feeder functionality
- AQ-F255D – distance protection + full feeder functionality
- AQ-F255E – line differential protection + distance protection + full feeder functionality
Highlights:
- Line differential protection for two line terminal ends uses Arcteq’s smart dedicated process bus that transfers both standard data and up to 64 user-defined signals. It automatically synchronizes line differential protection settings from the master node to the sub-node device, and compensates for communication delays without external time synchronization.
- Innovative line segment-based distance protection function enhances resistive reach and fault location accuracy, particularly in mixed networks, reducing the risk of unwanted operations.
- Low-voltage ride-through protection.
- IEC 62443-4-2 compliant cybersecurity (security level 1).
- A large I/O capacity.
- Optional power and energy measurement accuracy 0.2 %.
- IEC 61850 2nd Edition.
