The AQ-F213D feeder protection device provides optimal performance for medium-voltage (main) or high-voltage (back-up) protection, control and monitoring applications. AQ-F213D integrates protection, control, monitoring, measuring, communication and extensive diagnostics information in one compact package. The device has a fully modular hardware construction with three (3) empty I/O slots. This gives the device a high level of flexibility. You can simply plug in additional I/O or communication cards according to application needs.

The development of the AQ-F213D feeder protection device uses the latest available technologies, which provides protection engineers with more options and a completely new dimension to protection. The device has many features which guarantee its maximum usability. These include the highly customizable graphic interface, the ability to store PDF files and other supportive documents, and extensive user log information. Additionally, the powerful configuration and setting software tools are easy to configure and free of charge.

We offer five (5) variants of the AQ-F213x feeder protection device, A-E. AQ-F213D includes advanced feeder protections, such as directional overcurrent protection and over-/underfrequency protections. The D variant also includes the fault locator monitoring function.

Highlights:

• Directional earth fault protection.
• Over-, under-, and neutral overvoltage protections.
• Low-impedance restricted earth fault protection.
• Harmonics protection and control.
• A 5-shot scheme-controlled auto-recloser.
• IEC 61850 communication protocol, edition 1.
