32nd Annual Review May 20, 2011
University of Illinois at Urbana-Champaign Chris Lettow – Manager – Product Engineering
Who Is S&C Electric Company? • Specialists in electric
power switching and protection
• Headquartered in Chicago, USA
• Operations in five countries
• Employee-Owned • Annual sales ~ $500+ million USD • 2500 employees globally
What is the ATC? • A high-power testing laboratory • Located in S&C’s Chicago, IL industrial campus • 2 850MVA generators – 1700MVA total • Up to 100 kA and up to 230 kV • 43,000 Sq Ft facility • Environmentally Friendly
– City of Chicago Green Building Policy – LEED Gold Certification
• Affiliation with NEETRAC
Why Build the ATC? • Many reasons – but shortening product development
time is key • Prior to ATC construction, S&C’s previous High Power
Lab test capability was only 100MVA • Required testing at outside laboratories in Vancouver
and Holland • In addition to the cost of testing, this left development
teams little flexibility and required long “lag times” between test, analyze data, re-design and re-test
Why Build the ATC? • Previous High Power Lab provided ability for proof of
concept testing only – could usually not test any product to full rating – Example: 27kV, 12.5kA interrupter – could test only
as high as 8kV, 7.5kA • Lead times at outside laboratories usually very long and
often uncertain – difficult to factor in to development project schedule
• NEETRAC - National Electric Energy Testing Research & Applications Center
• Affiliated with Georgia Tech College of Engineering • Comprised of utilities, manufacturers and educators • S&C joined in 2009 • NEETRAC shared in funding of the ATC and will use
the ATC for its testing programs

Some of the LEED Stuff
LEED Efforts (Leadership in Energy & Environmental Design) • LEED – Gold Certification • Green/Energy Star roof • Recycling storm water for irrigation • High efficiency mercury-free lighting • Recycling construction materials and debris • Landscaping to shade parking areas • Committed to 24% minority and 4% women-owned local
business participation • Pursuing LEED certification for entire JRCIC
– 20 buildings – 45 acre site

ATC – Benefits Already Realized • ATC opened in January, 2010 • Innovation has always been crucial to S&C’s success – and the
ATC has already paid dividends! – Within first month of operation, increased testing capabilities
of ATC allowed us to perform testing required to expand interrupting rating of an existingo product
– Several ongoing development projects have been aided by
the ability to test, react and re-test quickly without the need for expensive travel and test preparations
– Engineers more engaged in the testing process - as “home” lab better understanding of components, lab capabilities and circuit setups
ATC – Benefits Soon to be Realized • Relationship with NEETRAC offers many benefits, chief among
them the ability to obtain 3rd Party Test Certifications in our own laboratory
• 3rd Party, independent certifications to industry standards (IEEE,
IEC) becoming required by more and more utilities – particularly internationally
• NEETRAC’s involvement allows outside customers to make use
of the ATC for their own use with confidentiality ensured • Separate control room for NEETRAC/outside customers off limits
to S&C personnel
