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.

Damn, that looks scary! Did your hairs stand-up while taking these pictures? 🙂
