How Do Substations Work?

Untangling the various equipment you might see in an electrical substation.

This is a very interesting video. Substations do a lot more then just stepping down the voltage from high-voltage transmission lines. They carefully control the output voltage and frequency, bring together often multiple power lines feeding into the system, they can disconnect and connect lines for servicing and repair. In many ways, substations really are the brains of the local power grid.

Rural electricifican

The other day driving past the hunting camps and rural homes up on the dirt roads around Gas Springs NY, I was a bit surprised how far the electric lines extended into this area to very remote farms and camps on dirt roads. I guess I shouldn’t have been surprised – rural electricifican has extended to nearly all corners of our country – but it seems like in an era of solar power, batteries and inverters, to be incredibly expensive and wasteful to have run lines all that way out there.

Power Lines

While rural electricifican efforts got underway in the 1930s, many of the more remote farms and homes didn’t get electricity until the 1950s or even 1960s. It seems hard to imagine a modern dairy without electricity to run the pumps or coolers but many other farms certainly did. They had all kinds of belt driven equipment that often ran off of Blackstone and other primitive motors. The modern tractor PTO had yet to be standardized.
