THURSDAY MARCH 23rd 2023 Seminar at the TTA Spring Meeting
Join us at the Transformer Association Spring Meeting for the Transformer Design Seminar hosted by Optimized Program Service. Event details can be viewed at https://www.transformer-assn.org/events/tta-spring-meeting-2023-a
To Register to attend the Basic Principles of Transformer Design Seminar please email opseast@opsprograms.com
Seminar will be held at Doubletree by Hilton Hotel Orlando Sea World.
10100 International Drive, Orlando FL 32821
Registration deadline is March 3.
After attending these seminars, you will feel confident to design without any application tools or software programs. These seminars are intended for technical personnel who want to learn and review the basic principles of transformer design from initial to end stages of the design. We will be providing design examples and concepts of transformer design using hand calculations.
Who should attend?
- Engineers looking to familiarize designing transformers by using hand calculations
- New OPS software users and engineers who will be using OPS in the future
For inquiries, please email opseast@opsprograms.com or call 440-238-0700. We are looking forward to seeing you at the event!
