According to the UFES Standard documentation , the system is built to handle high energy.
: Personnel should have electromechanical education and experience with medium-voltage technology.
High-speed current diagnostics detect the sudden spike in overcurrent.
By quenching the arc so quickly, the system reduces the pressure rise and thermal stress, often preventing any visible damage to the switchgear compartment. Benefits for Your Facility UFES™ Ultra-Fast Earthing Switch - ABB abb+ufes+manual
A simplified tripping unit that relies on external detection systems like ABB TVOC-2 or REA . 📊 Technical Specifications UFES™ Ultra-Fast Earthing Switch - ABB
Extinguishes arcs within
Available in different ratings matching standard switchgear voltages (e.g., up to 17.5 kV or 40.5 kV). According to the UFES Standard documentation , the
Imagine a scenario where ABB collaborates with UFES (as a representative of educational and research institutions) on projects that aim to fuse manual craftsmanship with technological innovation. Such collaborations could involve research in advanced robotics, development of new materials, or creation of more efficient industrial processes. Students and researchers at UFES could engage in hands-on projects sponsored by ABB, applying theoretical knowledge to real-world problems and developing solutions that blend manual dexterity with technological acumen.
By following this guide, you will reduce downtime, avoid costly mistakes, and ensure your ABB equipment operates safely and efficiently for years to come.
ABB offers a two-day training course structured as 40% theory and 60% hands-on practice, with a maximum of 5 participants per session. The course covers UFES technology, component functions, operation elements, installation, commissioning, and maintenance concepts. Upon completion, participants understand the constructional design, installation procedures, and safety rules. By quenching the arc so quickly, the system
: Type U1 units that use a micro gas generator and vacuum interrupter to achieve a closing time of less than 1.5 ms . Functional Overview
The primary switching elements (U1) are single-use devices and deform upon activation.Following a true arc fault event, you must replace all three U1 elements.Inspect the busbars for thermal damage caused by the initial micro-seconds of the arc.Replace the electronic coupling unit firing modules along with the primary elements.Test the entire installation thoroughly before re-energizing the switchgear lineup.
