an UFES in order not only to protect the investment from the effects of an arcing fault but also to increase personal safety to a maximum. A service kit is available for mounting on the transformer enclosure. – Retrofitting of existing ABB dry-type transformers: – ABB Service Box (up to 24 kV) The universal ABB UFES Service Box for

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. The Ultra-Fast Earthing Switch (UFES) is a combination of devices consisting of an electronic device and the corresponding primary switching elements which initiate a 3-phase fault to earth in the event of an arcing fault in the system. – ABB - Portfolio – productpresentation – information about ABB - Service – UFES technologie and components – funtions of the UFES components – display- and operation element of the trip electronic – connections of detection- and trip electronic – operation and installation – commissioning – maintenance concepts Your benefit An Overview of the ABB UFES active arc flash reduction solution Our November speaker will review various types of cable ties and their applications with respect to extreme conditions, The speaker will review application considerations including life expectancy, and economic issues. The REA family of relays is designed to protect medium and low voltage air-insulated switchgear against arc incidents.

The type-tested ABB UFES Service-Box can be used proprietary. It is mounted directly on the switchgear system, taking account of short-circuit strength, and connected by copper bars to the busbar of the switchgear system. Various installation configurations are possible to ensure flexibility in mounting of the UFES Service-Box at site: The UFES primary switching elements, installed in ABB withdrawable assembly or truck design, provides a simple opportunity to upgrade exist- ing switchgear systems with active arc fault protection • The contact with the busbars is established via the isolating contacts of the withdrawable assembly • The optimum Plug & Play solution when vacant panels are available • Similar solutions are also available for other switchgear types with trucks * The UFES (ultra-fast earthing switch) is a com- bination of devices consisting of an electronic device and the corresponding primary switch- ing elements which initiate a three-phase grounded bolted fault in the event of a fault. The Ultra-Fast Earthing Switch of type UFES is a combination of devices consisting of an electronic device and the corresponding primary switching elements which initiate a 3-phase short-circuit to earth in the event of a fault. UFES |Products – Catalogue9 Fig. 2.2.2-1 ABB Arc Guard type TVOC-2 2.2 Accessories and external components 2.2.1 UFES kit with TU type QRU100 The complete detection of an internal arc fault is done by means of external detection units. In this context, the TU suits ideal for the connection to the ABB arc protection system type REA. Ein aktiver Störlichtbogenschutz durch ein UFES System sorgt für Personen- und Anlagensicherheit auf höchster Ebene.

Innovativ minimering av ljusbågar på mindre än 4 ms: högsta möjliga nivå av ljusbågsskydd för personal och utrustning, underhåll av säker strömförsörjning och en minskning av produktionsstopp. UFES | Products – Catalogue 9 2.2 Accessories and external components 2.2.1 UFES kit with DTU type QRU1 The optical detection of the individual switchgear system compartments is done by means of single lens sensors, which are directly connected to the DTU. Furthermore, the system can be expanded with the ABB UFES protection mained in working condition. With this test, ABB also proved that this arc flash solution on medium/ low voltage systems using UFES is able to reduce the incident energy below (1) cal/ cm2. As per OSHA regulations, this brings the hazard risk cate-gory to zero.
