1 Premset : A New generation of MV Switchgear Amith Ganasram August 15, 2014

2 Schneider Electric 2 - Energy – Premset – Weili Ding - Sep 2013 Wiki : “Innovation is finding a better way of doing something. The term innovation can be defined as something original and, as a consequence, new, that "breaks into" the market or society.”

3 Schneider Electric 3 - Premset Openline What’s Premset and where is it sold ? ● Premset core technical application ● Compact, modular, smart ready switchgear ● Circuit breaker up to 17.5KV, 1250A, 25 KA 3s, IAC 25 KA 0,5s ● Market main application: ●Low-end Primary ●High End Secondary ●Targeted segments ● CIB : Commercial and Industrial Buildings ● Utility : MV/MV Substations ● Data Centres ● Hospital ● Industry ● MMM ● Infrastructure

4 Schneider Electric 4 - Energy – Premset – Weili Ding - Sep 2013 The 5 reasons why customers love Premset Safety of people and assets in any environments Highest efficiency and flexibility Smart-grid ready architecture Be the most reliable, compact and end-user friendly to operate Easy to maintain innovative technology (Shielded Solid Insulation System (2SIS)) with reduced risk of internal arcing highly modular and flexible design distributed intelligence that allows for easy integration, easy configuration, and enhanced efficiency through advanced monitoring and control. breaking-disconnecting-earthing functions in a single device with intuitive and fully interlocked operation Lowering the total cost of ownership and improving peace of mind

5 Schneider Electric 5 - Energy – Premset – Weili Ding - Sep 2013 Voice from Customers in MV Distribution network -“ you have to take in account the smart grid trend ” -“ expected life duration of switchgear is increasing ” -“ maintenance-free is far more important than SF6-free” -“ we want a switchgear with Easy Operation for our maintenance and operation teams” -“ cost effective and compact Circuit Breakers are needed for small primary substations or loop management ” -“ no problems with GIS switchgear, because reliable in harsh environment (humidity, temperature, dust, poor installation, partial discharges) ” -“ I’ll never compromise about end-users safety ”

6 Schneider Electric 6 - Energy – Premset – Weili Ding - Sep 2013 New generation of switchgear - Premset Premset

7 Schneider Electric 7 - Premset Openline Key Benefits Simple - Safe - Smart Safety Reliability Flexibility Efficiency

8 Schneider Electric 8 - Energy – Premset – Weili Ding - Sep 2013 Premset Totally Shielded Solid Insulation System design for optimized safety and extended equipment life Low Voltage cabinet 2- Cable test 3- Top connections 4 - Core unit 5 - Bottom connections 6 - Bottom compartment 7 - Sensors (CTs and VTs) 8 - Gas exhaust duct

9 Schneider Electric 9 - Energy – Premset – Weili Ding - Sep 2013 All surfaces at earth potential ● No dielectric ageing ● Long product life expectancy ● Reduced internal arc risk ● Accidentally touchable ● Insensitive to harsh environment Safety & Reliability - SSIS Totally Shielded Solid Insulation System design for optimized safety and extended equipment life

10 Schneider Electric 10 - Energy – Premset – Weili Ding - Sep 2013 Safety & Reliability - SSIS Well-known Technologies (epoxy, EPDM*) All surfaces at earth potential *EPDM: Ethylene Propylene Diene Monomer rubber Single bus bar (630A) Cable connection Busbars with shielded solid insulation Patented flat connectics Solid insulation covered by a conductive layer

11 Schneider Electric 11 - Energy – Premset – Weili Ding - Sep 2013 Safety & Reliability - SSIS Earth shield continuity ensured by Patented Flat Interface Main advantages compared with traditional conical interface ●Simplicity of installation ●Compactness ●Flexibility Flat interface cross-section Electrical field calculation.

12 Schneider Electric 12 - Energy – Premset – Weili Ding - Sep 2013 Safety & Reliability – 3 Position Scheme Disconnection in vacuum & earthing switch in controlled air ● redundancy of isolation - vacuum bottles for breaking and disconnection - controlled air for downstream earthing switch in sealed-for-life screened tank. Breaking and disconnection Earthing switch Operation of earthing switch Operation of main switch

13 Schneider Electric 13 - Energy – Premset – Weili Ding - Sep 2013 “The most intuitive operations for breaking, disconnection and earthing” 3-in-1 integrated architecture: easiest and safest operation, with built-in interlocking Safety & Reliability - Interlocking

14 Schneider Electric 14 - Energy – Premset – Weili Ding - Sep 2013 Safety & Reliability – 3 Position Scheme Disconnection in vacuum & earthing switch in controlled air

15 Schneider Electric 15 - Energy – Premset – Weili Ding - Sep 2013 Safety – Cable Testing Device Cable testing and diagnosis: dedicated device, for easy access and total safety ● Cable testing without accessing cable box or dismantling cable connections ● Test device connection from the front of the switchboard, while cables remain earthed ● Failsafe interlocks with earthed star point Easy cabling All cables connections are aligned in front at a height of 700 mm
