Immediately before the failure, the majority of power on the grid was inverter sourced, not rotating. I have heard talk of motorizing retired generator units in order to improve inertia of heavily solar/battery supplied grids.
One supplier of ours that uses John Deere engines has strict back pressure limits on the fuel returns. We have to run checks because we have multiple engines sharing common returns.
I haven't heard about this incident. The writing of the article is very strange and doesn't explain the situation well. This article does a little better but both have similar references so there must be a parent pre-AI article somewhere...
As an operator of propellers, its obvious by watching the wash of a propeller that the concept of a tidal generator is totally absurd. The wash rapidly expands and fans out due to turbulence in the fast moving water. Trying to reverse that process and convert a small cross section area of that...
If there was corrosion due to water I would expect pitting on surfaces. The report makes no mention of that and oddly ommitted all images of the parts that actually failed.
I have an issue with that report on the freewheel gear. They found corrosion products in the freewheel mechanism and assumed it was due to water intrusion despite no actual water being present and no sources of ingress found. Did the investigators not know of fretting corrosion? That will occur...
A typical self-priming centrifugal pump will lose prime and stop pumping before it pumps all the water out of its casing. It will continue to self-prime until water is available to pump again. It will self-prime as long as there are no checked valves on the discharge side of the pump. You may...
