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.

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...

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! |

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?
