The UFES is a smart combination of an arc detection system e.g. ABB´s REA or TVOC-2 systems, and the corresponding primary switching elements (PSE), which initiate a 3-phase short-circuit to earth in the event of an arc fault.

ABB UFES System; arc flash protection relay and ultra fast earthing switch to eliminate arcing faults in less than 4 mS. See NEPSI’s arc flash mitigation document for further details on arc flash mitigation.

I would like to start by thanking ABB for letting me do this thesis at “ABB AB As the name indicates, Ultra Fast Earthing Switch (UFES) is the product of ABB

UFES™ - Ultra-Fast Earthing Switch (English - pdf - Presentation) UFES™ - Ultra-Fast Earthing Switch - Active internal arc protection for low and medium voltage switchgear (English - pdf - Brochure) Internal arc test 100 ms without and with UFES intervention (UniGear ZS1 50 kA) - MP4 (English - mp4 - Movie) ABB UFES-servicebox (upp till 24 kV) Den typtestade ABB UFES-serviceboxen kan köpas loss för egen användning. Den monteras direkt på ställverkssystemet, med hänsyn till kortslutningstålighet, och ansluts till ställverkssystemets samlingsskena med kopparskenor.

ABB upgraded its market-leading range of Slimline XR low-voltage switch fuse disconnectors, reducing power losses by up to 35 percent and increasing potential space savings. A host of technical advances and design improvements make the Slimline XR range smart, with higher-performance and suitability for even more demanding applications.

ABB Library is a web tool for searching for documents related to ABB products and services. NEPSI is pleased to welcome ABB back for Tech Talk Session 40 where we will be presenting their ultra-fast earthing switch, UFES, an effective arc-flash miti Looking at ABB products, UFES is included in the accessory portfolio of various low- and medium-voltage AIS solutions e.g. UniGear ZS1, ZS8.4 or MNS. It is also available as an integral part of an enclosed RESIBLOC dry-type transformer solution. Outside ABB, also OEMs (original equipment manufacturers) benefit from the active protection approach. To clarify some confusion below the ABB UFES indeed will clear a fault in 4ms. The UFES is not relying on the Breaker to open in order to clear the fault. UFES works by activating a Micro Gas Generator located in the PSE module which creates a path to ground in 4ms or less.
