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. Slide 3 Schneider Electric 3 - Premset Openline Whats
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 Slide 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 Slide 5 Schneider Electric

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) - Ill
never compromise about end-users safety Slide 6 Schneider Electric

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 Slide 16 Schneider Electric

Interlocking Live cable interlock - Electrical lock-out of earthing
switch when live cables Earthing switch lock-out function - Prevent
the earthing switch to be closed on earth when cables are still
alive - Positively blocked in case of auxiliary power loss -
Override unlocking by key - Remote indication of locked position
