Reading Substations

Substation Medley

An electrical substation is laid out just like a schematic. Engineers, left to their own devices, don’t add much cruft. Yet they’re fascinating in their functionality. I’ve long been in the habit of noticing them, even pausing and taking pictures, but not having learned much in middle school about em, I was failing to look back.

I finally regressed to what should have been in my high school curriculum (if not middle school): the anatomy of a substation. Not just what it does (steps up voltage for long distance transmission; steps down voltage for end user loads) but its anatomy: air gap disconnectors; gas-infused circuit breakers; oil-cooled transformers.

Where this puzzle piece fits, for me, is into my School of Tomorrow curriculum, brought to you by Oregon Curriculum Network and my own little 4D Solutions. I’ve called it Martian Math, which is meant to signal the science fiction stories one finds therein. 

We use sci-fi in place of fairy tales, if there’s a difference. One such story features ETs wanting to work with Earthlings on a hydro-dam project and needing to learn how the Earthlings learn maths, so as to make ET-Earthling communications more productive.

Substations have some features in common with hearts. For example, the substation itself needs some power, to run its own internals, which likely includes a control house even if remote operations are more likely (it's not either/or). The heart snarfs some outgoing fully oxygenated blood right off the top, from the aorta, to feed heart muscles.

Also, when doing open heart surgery, the team is able to route the patient’s blood through the perfusion station where real time testing and corrective dosing may occur (I’m not the expert, but did work with such teams as a software engineer, usually after hours (when CVOR itself was off line)). Likewise workers tasked with maintenance don’t want a live load and it’s reassuring to see, with one’s own eyes, that the disconnectors are in their “open” position.
