Continued from my O/P: Here is the -328 temperature value shown in the trending. Thanks again, Scott I really am a good egg, I'm just a little scrambled!https://files.engineering.com/getfile.aspx?folder=fb79a020-6a70-4611-928e-881e98989927&file=trace_6.jpg

Hello all, We have a 2300V 1500hp Siemens motor Model:CGII frame:5812S that is giving us intermittent outer(rear) bearing temperature high faults. Now our control system monitors this and the trending I found showed temperature variations from a -328 degrees to 1562 degrees F. This was with...

ATSM D120 covers the rating of the glove class. Voltage will be known in your study and thereby determine which class of glove is required as well as the other PPE and boundaries. Scott I really am a good egg, I'm just a little scrambled!

It is always included in our A/F studies. Cheers, Scott I really am a good egg, I'm just a little scrambled!

Seems to me at one point in my life, I recall hearing that mixing a bit of 2 stroke oil in the petrol helps clean valves. On a petrol engine. I don't know, but go with the results you like. Cheers, Scott I really am a good egg, I'm just a little scrambled!

"But Captain, I canna change the laws of physics!" "well then Mr. Scott, you're fired. " It didn't shrapnel the radiator did it? This is why we have global warming. People like us blowing up 12 oz cans of freon. Oh and cow flatulence too! Cheers, Scott I really am a good egg, I'm just a...

Bus must be able to withstand the maximum amount short circuit current available in the given application. They must be braced to withstand that. Good luck on your finals. Cheers Scott Ps: google, over a million hits in 1.41 seconds I really am a good egg, I'm just a little scrambled!

Oh, the concave bottom of the can inverted (expediently) itself causing the can to jump off the core support. It also became very hot and it caused me to create this very bad smell! Stupid mistake with a very good outcome. Lucky Learning I call it. Cheers, Scott I really am a good egg, I'm...

I had a similar problem back when I first became a member here. I "upgraded" from an IRF 340 to a IRF 460 and neglected to take into account the increased gate capacitance. Started cooking IRF 460's. Well, the fine professionals here clued me in on the errors of my ways and I calculated the...

They were a couple of people that worked in apps at our sister company Laser Lab outta Cincinati. I thought they went to work for Bystronic when LL closed. But then again, maybe it was Cinci that Liz went to work for...We used to call her Laser Liz. Very pretty blonde girl as well. I really am...

Leave the states alone. I would get rid of that wart of a municipality that resides at 38°53?42?N 77°02?11?W Between Maryland and Virginia! Oh, I guess Mike already said that. Cheers Scott I really am a good egg, I'm just a little scrambled!

I have been using that very set of HF guages for years. The only problem I ever had was operator error. Opened the charge valve while the HP side valve was open. That coulda been really bad, especially when you consider the height the can was sitting at. I would be talking a few octaves higher...

Ouch! I used to know some pretty good peeps that went there in apps. Liz and Jeff. Last I heard anyway.....(circa 2000) Scott I really am a good egg, I'm just a little scrambled!

My answer is if the spikes are strong enough to breakdown the insulation in the windings therefore leading to arcing, yes. And the wife likes the smell of ozone....weird. Scott I really am a good egg, I'm just a little scrambled!

While I am not familiar with that particular laser, I would suggest that you investigate cooling water temps, flowrate, any restrictions? Investigation of the hv power supplies for airflow restriction or coolant if liquid cooled. Failed ventilation fans? Some power supplies have a central heat...

Thanks Guys. That is exactly what I meant. Poor choice of words on my part. And Steve, that fault during shutdown really only causes an inconvenience the next time we go to start that compressor because the control stays in a faulted state. And we start these remotely. This causes us to...

Wow! Lacajun, If you ever decide to leave the Engineering community, you may want to consider motivational speaking! STAR for you! Scott I really am a good egg, I'm just a little scrambled!

I was wondering, and explaining to the wife what critical speeds are. We run multiple stage compressors and one of them always faults on a vibration fault at shutdown. I figure it is passing thru a critical speed during wind down. We can stop this monitoring in the ladder of the control, no...

Good point Bill, My bad, I neglected to consider the "locked rotor" condition before replying. Thank you for pointing this out to me. Cheers, Scott I really am a good egg, I'm just a little scrambled!

I am way off my bases here, but can you not use a thicker plate? I was going to suggest machining the plate on the atmosphere side ( getting thicker) but that would serve to increase surface area and thus load. Hmmm, I think I better stick to what I know. Just trying to help. Scott I really...
