Innovation forMV distributionIntroducing Premset switchgear, a new wayto design, install, and operate MV networks

2Building asmarter futurewith reliable, efficient energy

Premset architecture:Innovation to meet your needsThe experience of a leaderin MV distributionA globalpartneryou cantrust4 000 000functions installed worldwide throughour existing rangesA global player with local capabilitiesSchneider Electric TM has 110 000 people in more than 100 countries dedicated todelivering reliable products and solutions. It’s this global reach that helps us ensurehigh quality and local project and service capabilities, no matter your location.Combining technologies for breakthrough innovationCombining our expertise in both air-insulated switchgear (AIS) and gas-insulatedswitchgear (GIS), we’re breaking new ground with the extremely reliableShielded Solid Insulation System (2SIS).Network management making you smart grid-readyAdd to this our familiarity with all aspects of MV network management and youhave a partner who knows what the smart grid will mean for your business,and how best to keep you at the forefront of technology.A new generation ofswitchgear technologyPremset TM architecture represents the future of MV distribution, embracing thesmart grid’s functionality and changing the way our industry views the design,installation, and operation of MV distribution installations.A technological breakthrough, opening the way tounprecedented safety, efficiency, and ease of use:> Safe andreliable in anyenvironment.Insulation and screeningof all live parts ensurea trouble-free servicelife, while SF6-freetechnology enhancespeace of mind.> Flexible, simple,modular, andfunctional.Easy to install and easyto use, with operatorfriendlyswitchgear andno servicing of mainunits thanks to 2SIS.> Smart gridready,distributedintelligence.Advanced protection,control and monitoring,fully integrated forhigher dependabilityand energy efficiency.3

EfficiencySmart grid and advanced digitalmanagement solutions across your networkThe electricity market is changing. Every day, end-users’ expectations increase and suppliersworldwide gain a greater awareness of energy’s environmental impact. Meanwhile, overallconsumption is steadily growing. But as this reliance on electricity grows globally, the waysin which we produce, distribute, and use energy must also evolve. The solution will involvenot only smarter demand, but also smarter supply and a smarter grid.Intelligent, smart grid-readysolutionsTo meet these challenges, we need to enhanceour electrical distribution networks with intelligent,smart grid-ready solutions that bring a new level ofefficiency through advanced monitoring and control.This is precisely what Premset architecture isdesigned to do, enhancing your installationwith such features as:> > Feeder automation, with switchgearincluding built-in communication andlocal intelligence> > Load management, with integratedsmart metering> > Asset management, with advancedswitchgear and transformer monitoring> > Automatic Transfer System, withintegrated source transfer solution toreduce power supply interruption.Architecture with distributedintelligenceThe intelligent electronic devices used inPremset solutions allow easy integration,based on a standard communications protocol,with a plug-and-play scanning system foreasy configuration.All this adds up to a flexible system with integratedWeb technology, pre-engineered and pre-tested,which you can easily upgrade as necessary.With Premset architecture, you can easily builda smarter MV distribution system.CommunicationNetworkRadio / GSM /GPRS / EthernetIntelligentElectronic DevicesFault detectionProtectionMeasurementLocal controlRemote control4

ReliabilityLong-lasting performance with theShielded Solid Insulation System (2SIS)In addition to its impressive ability to maintain optimal performance in any environment,the Shielded Solid Insulation System is also the combination of robustness with a flexibleand modular design, allowing its functional blocks to be used in any combination.Extending protection tothe entire switchgearWhile insulation has previously been used,Premset switchgear is the first global productusing solid and shielded insulation.The system is applicable for all networkfunctions, including:> > Load break switches or circuit breakers> > Integrated metering unit> > Current and voltage transformers.Enhanced safety, reducedinternal arcing riskThe earth shielded system helps to extendthe equipment service life, resulting a lowertotal cost of ownership (TCO).Shielded SolidInsulation System(2SIS)And, with no part of the main circuit exposedto free air, you'll also:> > Reduce risk of internal arcing> > Require no maintenance> > Improve the safety of people and assets.2SIS is applicable forany switching functionsuch as load breakswitches or circuitbreakers, newcompact meteringfunctions, orcurrent and voltagetransformers.5

1Same design forevery configuration2High modularity with total insulation3456Premset system architecture is based on typetestedassemblies of functional blocks which aredesigned to work together in every combination.This simplifies the design and use of your MVswitchgear. In addition, the plug and play designof accessories and auxiliaries makes even lastminute or field modifications possible.Mix-and-match control, monitoring, MV functions,field upgradeability, and servicing ensure the mostcost-effective configurations.These modular options also:> > Improve cost savings> > Optimize delivery times> > Facilitate modifications.The offer also includes a consistent range ofcompact, reliable circuit breakers, from thesimplest MV/LV transformer circuit breakers to theheavy-duty line protection functions. These have allbeen optimized with a highly competitive market inmind, guaranteed to deliver the best performanceat optimized cost.1 LV cabinet2 Cable test3 Top connection4 Core unit5 Bottom connection6 Bottom compartment6

FlexibilityA compact and modular designfor all functionsPremset range is a functional switchgear, with the added advantage of being both simplifiedand modular. The end result is a system that is easy to choose, easy to use, cost effective,and facilitates both simple installation and modification.Fast, stress-free installation,upgrading, and maintenanceBecause the range uses the same design for everyconfiguration, customizing the switchgear to yourneeds is easier than ever before. And with itsstandardized dimensions, reduced footprint, andsimple front power connections, time and moneyspent installing Premset switchgear is greatly reduced.Modular combinationOptimizedcircuit breakersEvery aspect of the system is designed with theintention of making installation and adaptationsas seamless as possible, including:> > Straightforward assembly becauseidentical busbar and cable connectionsare used for the entire range> > Easy-to-install patented universal flatpower connection system> > Easy cabling since all cables connectionsare at a height of 700 mm> > No preventive maintenance andservicing required.Upgrading is easy, with the same auxiliaries,accessories and monitoring devices being used forthe entire range. In fact, this 'plug and play' designalso allows on-site additions that do not require anyspecial training, tools, or adjustments.Lastly, end-of-life management is easier, becausethe SF6-free design means there are far fewer labourand administrative considerations.3 waysthat total cost ofownership (TCO)is reduced:1 2 3Up to 30%Easy cablingThe increase in lifeexpectancy due tothe absence ofpressurized gases.Trouble-freeinstallationWith an up to 50%reduction in footprint.(Width dimension of the circuitbreaker is reduced by 1/2).All cables connectionsare aligned in front ata height of 700 mm,along with extendedpossibilities of cableentry arrangements(bottom-front, bottomrear,top-rear, etc.).7
