The ABB UFES (Uninterruptible Frequency and Voltage Stabilization) system is a sophisticated power quality solution designed to provide reliable and clean power to sensitive equipment and critical loads. As a leading provider of power system solutions, ABB has developed the UFES system to address the growing need for high-performance power quality solutions in various industries, including data centers, healthcare, finance, and industrial manufacturing.

According to the UFES Technical Guide, the system consists of two primary parts:

: The fault current is finally cleared by the feeder circuit-breaker, which may also be triggered by the UFES electronics to shorten total breaking time. Key Technical Specifications Rated Voltage Up to 40.5 kV Rated Short-Time Current Up to 100 kA Switching Time (PSE) Total Extinguishing Time < 4 ms (after detection) Service Life Expectancy Up to 30 years Installation and Retrofitting abb+ufes+manual

: The PSEs establish a 3-phase earthing, breaking the arc voltage and extinguishing the arc well before the first peak of the fault current.

If you are referring to and UFES (Universidade Federal do Espírito Santo) , this could involve: Key Technical Specifications Rated Voltage Up to 40

For detailed technical specifications, wiring, and installation, refer to the ABB Library for UFES documentation.
