Transformers are one of the most critical—and most misunderstood—parts of the power system. So we made a new Giga Field Guide to break it all down in 3 minutes:  - How transformers actually work - Why stepping voltage up and down powers the entire grid - The difference between single-phase and three-phase - Why AC is essential - And what really happens inside the core We design and build transformers for every application so you always get the right voltage, the right performance, and the right support.
