The comprehensive range of devices delivers safe and stable protection and offers decisive advantages. From the integrated and super-fast PLC, to configurable protection functions and the easy-to-use signal matrix. The thoroughly experienced Arcteq developers are constantly setting new standards. Many of the novel functions and extensions are patented and stand for innovation at the highest level.
The patented input circuit of the Arcteq protection relays delivers the highest accuracy and makes the devices world champions. The precision paired with powerful protection functions provides a perfect platform for demanding protection applications.
The input circuit of the Arcteq protection devices enables frequency-independent measurement with previously unattained resolution and detail accuracy over the measuring range of 6-75Hz. Measurement (class 02S) and protection in one device become possible.
Arcteq's top mains protection devices are produced entirely in Finland. Based in Vaasa, Finland, Arcteq is renowned for manufacturing the world's most precise protective relays. Arcteq is also a pioneer and technology leader in the field of arc fault protection.
The free AQtivate 200 software saves valuable development time through an intuitive and easy-to-use interface. The changeover to the Arcteq protection devices can be managed without any problems. The logical structure makes the set-up easy to understand. The software tools support programming and commissioning. The configurations created in this way are comprehensible and can therefore be easily maintained. We accompany you through all phases of your projects and are there for you if needed.
In recent years, Arcteq products have been installed all over the world. In addition to high-quality products, we are committed to providing our customers with industry-leading support and service.
The modular design reduces the spare parts stock. In addition, you can expand our protective relays directly on the system if required. These are decisive factors in giving you maximum flexibility in operation and for your projects.
The graphic display of the protective relays is fully configurable. In addition to the display of switching objects and measured values, the lines of the single line diagram can be topologically coloured. Status-dependent message displays support troubleshooting and provide clear visibility. The large display enables comprehensive representations of all system parts (e.g. several feeders on one display or switch representation of the opposite side). The designations are clear and understandable and thus increase the operational safety in your network.
Communication: everything included
Ethernet communication ensures fast and seamless data transmission. Our protection devices communicate via a variety of standard protocols, including the IEC 61850 communication standard for substations and the fast GOOSE.
In recent years, the application of arc fault protection based on light sensor technology has become the new norm of current-loaded installations.
In addition to protecting people, the aim of protective measures is also to maintain plant function and minimise operational downtime. Arcteq is the pioneer and technology leader in arc fault protection. The design and production of these high-tech products are 100% carried out in Finland.
