Arcteq protection relays in Swedish utility
Arcteq has installed Feeder Protection IEDs, Transformer Protection IEDs, arc protection units, and arc light sensors to Kalmar Energi H3 110/12kV substation.
AQ-50 fault detection devices are accompanied by free-of-charge software tools that make configuring and updating the devices easy.

All AQ-50 devices have a built-in web interface for local and remote access via TCP/IP. The interface allows you to access the device’s status information and configure the device. The Site Manager feature provides real-time information about the devices and facilitates commissioning. You can also use it to update the device firmware and download fault recordings.
With the Device Manager you can manage an entire fleet of installed fault detection devices from a single tool. The Device Manager’s powerful features support both individual and batch firmware updates for the devices in the network. It also scans the devices in the network and presents the results to users for further actions. If the web browser tool is not enough for your application, the Device Manager is for you.
If you want to use the Device Manager, connect to your AQ 50 device with USB, or convert the events into a COMTRADE file, please contact us for the necessary software files and instructions on how to use them effectively!
