Our data center guys are putting in new power feeds. As part of this they need to step the incoming three-phase AC power down to 208 V, so they need a transformer. Four of them, actually.

People rarely get a chance to see and appreciate these sorts of things, so I snapped a couple of photos.

Note the different terminals on the windings (the yellow part). That determines the output voltage of the transformer. They build a one-size-fits-all transformer and make the connection based on your needs.

Now if these transformers would change into big alien robotic helpers in the data center we’d be in business.
