Arc quenching devices
Arcteq’s arc quenching devices operate in less than 4 milliseconds to protect human life and minimize arc flash damage to equipment. The quenching devices offer the highest level of protection in both new builds and retrofit projects, in both LV and MV applications. They can always be re-activated for multiple operations and testing, which makes them a cost-efficient and sustainable solutions for mitigating arc flash incidents.
When arc quenching is included in the arc protection system, the quenching device absorbs the incident energy, and the arc flash is extinguished before heat, pressure and gas emissions arise to dangerous levels and the impact of the arc flash is mitigated. This minimizes the impact of the arc flash on people and equipment.
- Operate in less than 4 milliseconds.
- Operate based on reliable two-criteria detection of an arc flash.
- Can be re-activated for testing and multiple operations, making the cost-efficient and sustainable.

How to secure both the critical power supply and the safety of personnel working with switchgear that is not arc-resistant? In this webinar Managing Director Juha Arvola gives a case study of Stora Enso’s pulp and paper mill in Anjala where the goal was to prolong the lifetime of their 1976 substation by retrofitting circuit breakers and protection relays, as well as by installing a resettable arc quenching device. With the arc energy levels close to zero, they have now secured both their personnel and critical power supply for the next couple of decades.
Product Manager for Arc Protection Mikko Manninen gives a practical approach how to test the AQ-1000 arc quenching device with the test setup. This webinar includes the basic installation rules and guidelines, timing tests with oscillographs, and how to use the commissioning switch.

Sales and Marketing Manager Robert Olander explains how the ultimate personnel and process security is reached under the extreme conditions of an offshore drilling rig. This webinar is based on the Norwegian Island Drilling Company which Arcteq supplies with arc quenching systems through our partner Mongstad TavleTeknikk.
