Investing in Innovation S&C Electric Company’s

Advanced Technology Center The Power Affiliates Program

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

ATC One-Line

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

Aerial Shot of ATC

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
