Steel Mill roller tables (and other related equipment nearby) have high temperatures in some areas (radiant heat from hot slabs and plates), continuous wet conditions in some areas, and water splashed conditions in other areas. The water is typically 35-40C although there is steam generation...
I think it depends on the value of the process, and details of the load.
For example, if you can drop 40% load in an emergency, then you could purchase two transformers, each with 60% capacity.
//All 8 core bolts were replaced and positively grounded//
Would that stop the circulating currents, or increase them? Were the materials correct?
The opposite direction would be, of course, to insulate them.
itsmoked, I don't know the details of why you have nine connections and so on, but I would suggest perhaps there is a difference in reactance on each phase of the motor. Effective reactance will obviously depend on winding details, iron core but also the speed of the motor at different angles of...
rxmelaun, there is another, older, method which I came across once: If you could get some samples of known crankshaft material and use a high speed grinder, then you could compare the sparks from the known types to the unknown type. Perhaps if you got someone to photograph the results it might...
I assume it is a ladle transfer car that you are talking about. Can you find a reel that doesn't have brushes? This would surely be the biggest problem.
I would suggest that you review the wireless system again - if you can get it to work, it would save a potential maintenance problem.
May I...
Reminds me of my apprenticeship days in the steel works: I noticed that to isolate an un-identifiable cable one dubious practice was to short it out, and rely on the fuse or circuit breaker to trip. That was until one 6 inch nail which had been hammered into the cable started glowing bright red...
There is a direct JIS standard: SNB16(see link).

Also see ASTM comparison for SNB16:

There are also microwave based instruments, which I think are intrusive.
AK2DM, you didn't mention what kind of accuracy you wanted in your measurement. Each device in your cabinet will produce a counter emf depending on its dissimilar metals and local temperature. I suppose that these will be averaged and each device will have more error (one will read higher than...
Ah, with that kind of speed, and small target size, I would suggest a line laser (not expensive), and a cut-down fresnel lens to convert the diverging light back to parallel. That's the transmitting part finished.
The receiving part could be a long line of individual photodiodes, as the object...
