Con Ed can’t explain what caused the Manhattan blackout
- tyingq 7y ago"the power is lowered to about 13,000 volts before being distributed to homes and businesses" They've left off a bit of detail here :)
- usbseeker 7y agoWhat don't you get? Power goes in one end and out the other, doesn't seem too complicated, thr problem was somewhere in the middle. Lmao
- JshWright 7y agoThe parent comment is pointing out that there are additional voltage drops before it gets to "homes and businesses". The electrical outlet in your wall does not supply 13,000 volts.
- nomel 7y agoTo be fair, this is equivalent to mentioning your home router when an ISP has an outage.
- Meerax 7y ago13000 volts to your home toaster is a bit of a problem don't you think?
- bad-joke 7y agoNot if you've installed Linux on it to run Folding@home!
- ozzmotik 7y agohey look it's a case study of nominative determinism in action! that being said, i approve
- Nexxius 7y agoNot if you are a Decepticon or Cylon...I mean really man, think of of your AI opressors for once. <<insert fav Decepticon toaster meme>>
- lykr0n 7y agoI presume they left out that 13kV is what the street level transformers get- which in turn will turn into 240v split phase, 240v three phase, or 480v three phase.
- Glawen 7y agoIsn't 120v the norm in the US ? In France, every home has a three phase 400V coming from the utility, then you choose if you want single phase or three phase in your home.
- frosted-flakes 7y agoIn 240 V split phase, each phase is 120 V.
- snowwindwaves 7y agoI had to determine why a single hydro electric generator kept on going off-line last week. Turned out to be a temperature sensor in the generator gone bad or high resistance connection in that circuit. Due to improper historical logging of alarms, older protection relays, etc, it took a visit to the power plant and a few hours of downloading and analyzing event files and correlating signals with the schematics. So a massive outage like NYC has just experienced will take weeks to collect the event files and analyze them. Probably the time was wrong in some places as well so it will be hard to figure out the exact sequence of events.
- anbop 7y agoSounds like a cool job. What is the job title?
- snowwindwaves 7y agoelectrical engineer or power station operator
- bgun 7y agoFirst sentence of the article "Con Ed has yet to figure out..." should be the headline, but I'm sure the more dramatic version got more clicks.
- noir_lord 7y agoShould be but then people wouldn't click the article to find out why big professional organization is inept thereby confirming their biases and giving them that lovely little frisson and dopamine hit.
- simtel20 7y agoAt a prior job we had our data centers in the building in that neighborhood. Because it had grown up with the computers down the hall and then down the elevator it was hard to sell upper management on moving to a real data center. What finally made the case was multiple summer power outages because con ed couldn't tell us how much power was actually possible to be drawn in the neighborhood. Between theaters turning up stage lights a couple of times a day, companies with data centers etc. It turns out that con ed has just run wires for a long time where requested without an overall tally of what the peak draw could be. This event was predictable, and if con ed or the city doesn't actually count the peak possible capacity going to each customer and make sure it can provide that, power outages in that neighborhood will continue to happen going forward.
- QuickToBan 7y agoWhat did Con Ed have to do to bring the power back? Or did they just "power cycle" it? Would Con Ed even be able to determine in case this was a cyber attack?
- Fjolsvith 7y agoMeh. Its a numbers thing. 42nd Street, 42 years (to the day) since the last big blackout, 42k people without power. What else does the number 42 signify?
- credit_guy 7y agoWell, of course 42 is an encoding of the number of the beast 6x6+6. See also [1] https://www.reddit.com/r/FanTheories/comments/24uio5/the_truth_behind_42_being_the_meaning_of_life_the/ https://www.reddit.com/r/FanTheories/comments/24uio5/the_tru...

- Fjolsvith 7y agoHeard a theory that it was part of an attempt to get to Epstein to do him in, because of all the people he could implicate.
