Electrical Transformation

Three-Phase Transformation of high-voltage electricity

The past few weeks have been challenging for outdoor work due to the rapid change between stormy, dark and rainy weather and a few minutes of bright sunlight when the sun peeks out from behind the clouds.

It was an unpredictable and amazing light which made an industrial landscape beautiful. Well, it was beautiful to me which is why I'm sharing it with you.

Electricity created by power plants is transported across the state and/or across countries at very high voltage between 220,000 and 380,000 volts.

An electrical substation serves to transform the electricity into voltage which can be consumed by households and businesses. The transformation cannot be done all at once but rather in a series of steps.

Today, the open-air transformers (photo #1) step down the three-phases from 220,000 volts to medium voltage of 35,000 - 10,000 volts. Photo #2 shows the transformers for medium to low (400- 230) voltage.

This electrical substation is undergoing construction until 2022 to be able to transform ultra high-voltage transmissions of 380,000 volts down to 110,000 volts. I won't be able to capture those transformers since they will be inside a dedicated building once completed.

I find it interesting that the substation also handles the electricity which the individual houses are generating with their photovoltaic panels. Thus, not only can a substation deliver electricity from the power plants to the houses, it also delivers electricity being generated by the houses back into the network.

Soon our house will be contributing to the network as we are planning to install photovoltaic.

Have you ever passed by a subject regularly with the thought "someday I'm going to capture that"? The substation offers interesting compositional elements such as groups of three's, straight lines and curves, and patterns.

That day was Monday for the substation and the window of opportunity for photography was only open for 15 minutes.

I wanted to capture more, but the sun was gone without warning. I switched to black and white for photo #3 before stopping altogether as the rain came.

It's probably a good thing too that I stopped, since the station is under video survelliance. I'm sure my zoom lens would have drawn some attention from the security agents if I had spent more time there.

You made good use of that window of time to create some interesting images from what most people would consider boring subjects. Good job, Lee.

Thanks Benny! If I scout out a location in advance, then I can be quick, but usually I‘m not. I‘m fascinated by industrial landscapes. It seems not to have the same popularity as romantic landscape (Heidelberg love locks…) Beauty is in the eye of the beholder.
