Some shots from the new HVDC-Center in Dortmund, taken with my Sony A7II and the R-Elmarits 2.8/35mm and 2.8/90mm on
the Techart LM-EA7 Adaptor.

The HVDC hall is 35 meters long and 25 meters wide, the height is 23 meters. An equally large open space testing area plus outbuilding and traffic area complete the center. The system can generate voltages of up to 1.2 million volts, breaking new ground in power transmission. The exceptionally high voltage is provided by a special device from the USA. The Voltage Regulator can produce bipolar voltages up to + 1.2 million volts and independently in a second cascade -1.2 million volts. This makes it possible to test various components for DC transmission technology such as cables or insulators.

Like 1 Like 1 VERY nice Wolf! Reminds me of my time when I did my PhD in El. Engineering at TU Darmstadt!!

HGÜ (Hochspannungs-Gleichstrom-Übertragung) was a big thing back then, used in Africa for very long distance power
transmission. Was dropped later, but now it is back in fashion...

An installation Tesla would love.
Would love to see the corona off that system at night.
Very cool, beats the Tesla coil I got to play with in the highschool electronics lab.

Well, TESLA working with high frequency high voltage. THis frequency here is ZERO, DC voltage Laugh 1

nope, that would be static high voltage only, low power.
This is Mega/Gigawatts behind it...

Well chosen object and very nicely processed, congratulations!

I find a subtle but a very distinctive feature that different lenses give in the way they render chromium reflex. Some lenses do that like "nothing special", some value it and bring with it a special mood to the whole picture. Your shots definitely go to the second type. The mystic chrome!

Ozone!

Very cool facility, must be exciting to watch when live.

Edison would approve, not Tesla...

Thanks for posting the pics! The 35mm is an early version, the 90mm later. Both are handsome and high performing lenses. Are you using a Leica R->M adapter between these R lenses and your Techart Lm-EA7?

I would love to see more from your elmarits.

Best regards
