glynnenstein posted:Those terminals are labeled right under the picture. Siemens soft starters that we installed because someone complained that the lights blinked on startup inrush. No joke. The lights flicked for 1/10th of a second. It did stop it, at least. Oh yeah. I have a power quality meter that can quantifiably measure both short and long term flicker (PST and PLT). I don't mind soft starters but with any drive system I get concerned about power quality problems. Mainly plant issues that can both crash the drive like a capacitor switching transient causing a DC link bus overvoltage trip, or the drive itself spraying harmful harmonics back upstream. You get "Hey whenever this equipment is running the UPS freaks out" problems. We've gone as far as installing isolation transformers and line reactors. I really prefer line reactors because they are cheaper to buy and install. But if you have an isolation transformer you get better isolation and generally you can adjust the voltage taps. If you have a big lineup with older drives you can install specially designed phase-shifting (zig-zag) transformers to help prevent situations where all the SCRs are firing at the same angle. Probably not as big a deal with IGBTs or other power semiconductors that aren't SCRs. Three-Phase fucked around with this message at 02:07 on Jun 13, 2017 |

It won't stay inflated like that for long, which is why they hook up the proper air hose at the end of the clip. Relevant Mythbusters segment

OSHA topic: Slip Resistant footwear. Everything SR-Max makes with this tread pattern is goddamn magic. https://www.srmax.com/mens-shoes/products/SRM2660 Ripping off winter-tire design puts these so far beyond everything else I've ever worn it's shocking, I can tap dance in the lathe oil pan now. It's a genuine shame they aren't doing better marketing or licensing the technology to brands people have heard of because Timberland Pro is straight garbage.

At least by the point where his body is literally on fire he was probably not conscious due to respiratory paralysis and/or fibrillation stopping the circulation of blood to the brain. And yeah scaffolds and ladders versus overhead lines are not an uncommon way for people to get fried. Or brooms I guess. https://youtu.be/XsNKua3vG1k I remember a long time ago seeing a custom warning sign on a cabinet that said something like "4160V THIS WILL POP YOUR rear end".

Stepped on two of those square cap roof nails right at the start of work today. Then the county came in 2 hours later and issued a stop work sending like 15 people home. The burly looking AC guys booked it out the back of the house to their car and dipped so fast even leaving their tools behind when the inspector started asking them questions. She was loving livid and sat down at the end of the street for like 4 hours hoping they would come back. Painters need no permits/licenses in that county apparently tho so we were all right lol But yea I should not wear running shoes to construction sites Fallows fucked around with this message at 03:23 on Jun 14, 2017 |

Well, you don't have to guess at it being aluminum cladding, they just installed ACM cladding a few months ago. Also the fire happened around 2-3 AM local, so of course everyone in the 120 units was at home and probably asleep. Plus there was the new smoke evacuation system: quote:...the new smoke extract system has been commissioned and is fully operational. This links the whole building including the basement plant room, so that if there is a fire, the system kicks in with smoke extraction/ventilation as necessary.
