    Thank you for Attending the OPS Seminar

    Optimized Program Service, LLC. recently held its Annual Optimized Program Service Instructional Workshop on September 17th-18th. Transformer design and manufacturing engineers, specialists, suppliers, and colleagues from around the globe gathered here in Cleveland, Ohio. The seminar was a great success as we featured the new version of our software. The two-day instructional workshop featured discussions on new additions to the software, tools to get specific results using the software, 2016 DOE efficiency standards and much more.
