The Blueprint Series - Power Systems Design Workshop 2 (Part 2)
Workshop 2 (Part 2): The Blueprint Series
Now it’s decision time. In this session, participants move from load estimation to sizing the heart of the system—transformers.
Through a practical, step-by-step approach, you’ll learn to select the right transformer rating, apply design margins, and plan for future expansion like a real engineer. With a focused worked example, you won’t just choose—you’ll justify every decision under competitive standards.
Think ahead. Size it right. Build for the future. Compete to win.
