I’m lost on the tour? The tour must have been abbreviated? Did I blink my eye? Where did he say the flux capacitor was? I saw the narrow backs in the switch house-check. Lots of bus work & disconnects-check. Flux capacitor?
Nice video! I’m a fan of and photographer of all things powerpoles and lines. Wish this had been more involved and thus a longer video as I’m trying to add more and varied info about electricity & it’s distribution to my knowledge.

for a quick knowledge about different components of substation please watch the video . ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-p_0eHBiKxQ0.html
@@aamirawan7998 You are almost correct. A regular AC transformer can't do it. You need what basically amounts to a switching power supply. I found a lot of info on this on Wikipedia: en.wikipedia.org/wiki/High-voltage_direct_current
maybe one day, but the amount of extra switching tech that is requiered is not effecient for those small substations, so they would stay ac forever and only the real "high-voltage" lines at hundrets of KV would be dc
If its in California I think they use 66kV out there not 69kV like where I'm in the midwest. Also their 12kV is typically exactly that - 12000V nominal. Different voltage systems out there than in the midwest. California distribution started out mainly as delta so transfomrers were wound for 12000V. Over time, utilities like SCE have been changing over to WYE systems so you have 12000Y/6930V. Here in the midwest we used to have 7200V delta systems and then they were upconverted to wye systems, thus came 12,470Y/7200V. Existing transformer units were changed to be wye connected instead of delta.
cybhunter007 one of the benefits of wye distribution is that you only need to run one hot wire into residential areas (along with the neutral of course) while all delta systems consist of two or three hot wires on the primary distribution lines.

They might have designed the station for higher BIL for future conversion to a higher voltage. Or just designed with higher BIL as an insurance policy.
