The FAA and its sister agencies around the globe are very good at root-cause analysis. Where a single fault could cost many lives, there's strong incentive to follow any failure all the way back.
I'm guessing that your systems don't experience anything like airplane levels of vibration, or have anything like airplane numbers of fatalities if the controls fail, yeah?
- generatorguy 7y agothey are turbine generators in hydro electric power plants - they are live buildings; the floor and walls are resisting all of the torque from the generators and the forces exerted by the water flowing through the building, and the machines are vibrating at 1 mm/s velocity or about 4/1000" displacement. So it isn't completely stationary, everything is just kind of humming and rumbling - unless there is a short circuit out on the power system and then massive forces are exerted on the generator and power conductors, or if the machine becomes disconnected from the power system and has 10 MW coming in and 0 MW going out it tends to speed up quite rapidly and shake a bit more - but for the most part I can't imagine any conductors wearing through their insulation, ever. No wires are ever exposed to sharp edges.
- drunken-serval 7y agoIn the US, the NTSB does root-cause analysis and makes recommendations to the FAA. There’s a separation of concerns. The NTSB is solely concerned with finding out what happened. The FBI handles criminal investigations. The FAA is concerned with running air traffic control, regulations, and research.
