These are in China. He talks about ten thousand volts. However those huge cables are carrying 700,000 volts! At thousands of amps! That ginormous amount of power would vaporize a person in an instant! https://www.facebook.com/100009308115158/posts/pfbid02nRTQveERffC2ZLGMzk5UPKnZhmXrhn6BZ5HLJ8krc8B2uqzUYJ38kUpLEzWs9buFl/?mibextid=Nif5oz

2024-11-11 Ultra High Voltage Workers In China
Notice the second worker clamping the conductor into that hexagonal ring. Wow! Each conductor is the size of his wrist! But it’s even more amazing there are *six* of them in each bundle! There are 3 or 6 of the bundles, and each bundle is held up by hugh insulators. Each bundle of 6 conductors

2024-05-15 Reconductoring Transmission Lines
Good article a few months old. JHAT recently had this reconductoring topic. This article also describes the Heimdall Ball temperature monitoring. One thing that has not been talked about is the use of BESS – battery energy storage systems – to reduce the peak load on the transmission lines. That’s what they did in Australia

2024-04-14 Drone Recharges From HV AC line
Wow! It just clips onto the HV cable and recharges while it’s hanging there. Presumably the drone has an inductive pickup coil that’s up against the conductor that’s carrying hundreds of amps. I bet Joe Tegtmeyer would like to have one of these! https://www.facebook.com/interestingengineering/videos/1123581112297321/?mibextid=NnVzG8 https://www.facebook.com/reel/415716777728231?mibextid=9drbnH&s=yWDuG2&fs=e
2023-11-20 Will HVDC Across Oceans Be The Future?
Engineering with Rosie Barnes explains HVDC and underground and undersea cables. Including the Xlink from Morocco to the UK, Basslink Tasmania to Australia, and the longest, Australia to Singapore. She believes that all the continents will be linked. Says there are plans for undersea HVDC cables between the UK and Newfoundland. It’s a 13.5 min

2023-10-22 Do-it-yourself Power Strips – True Story
We used similar “homemade” outlets on extension cords – we must’ve had more than a hundred around campus. But the fire inspectors wrote us up for using them in permanent locations under desks. We had to change them to commercial power strips. But I set up a temporary registration and add/drop classes area every semester,

2023-06-24 Never Defeat The Fuse! Or Fusible Link
I saw that meme where some clown replaced the 30 amp fuse in his car with a live .22 long rifle cartridge. That was a disaster waiting to happen! This is a true story – mid 1970s. My neighbor bought his wife a new sleek red Trans Am, and really loved how fast it could

2021-12-21 RS-232 Sharing Box, RS-485, Poll-Select, Etc.
I had hundreds of CRT terminals around campus, connected to 16 RS-232 ports on the mainframe computer, back in the ’80s and ’90s. The protocol was Burroughs poll-select. Each of a dozen or so terminals was given its own address by dip switch. They were all running at 9600 bps over telephone lines driven by

2020-10-21 Wiring Harnesses And Automation
I worked at a company that built automated test equipment for assembling cables and wiring harnesses. During the year I was there they sent reps to Detroit to help GM build wiring harnesses for Buicks. This was in 1980 and GM was using relays to implement the logic system to assure that the wiring harness
