Gene1203,
Are you the supplier of this unit? I suppose this unit is still under warranty. Then, the supplier should provide the services to determine the problem and the appropriate solution.
In addition to previous suggestions, I noted from the information you provided, "One report...
Recording/logging parameters might prove the problem but may not solve it. And, waiting for the problem to happen again is not a good idea at all. Since you have 3 units (assuming similar), then you must have spare voltage regulator, rectifier assembly, potentiometer, fuse, etc. Why not use...
In engineering, if you are a hiring manager what qualifications are most impressive? Please explain.
1. Education (Undergraduate, Graduate, etc.)
2. Experience (Entry level, 2yrs., 5yrs., etc.)
3. Skills, Communications (Oral and Written)
4. Skills, Technical (Designs, Codes, Calculations...

Building a single AVR for the first time may cost you even higher than buying original or prototype ones and definitely will be time consuming. You will have to design and fabricate the mounting and enclosure, look for the correct heatsink for the SCR's and...
Specifications are normally based if not totally copied by consultants/designers (Upps.. sorry for my words.) from equipment manufacturers' catalogues and manuals. In practice, some are specifying to recommend (a specific product and earn extra bucks).
About load shedding and load management...
Schematic Diagrams are available only from the AVR manufacturer, authorized service centers and/or other company or individual involved in sales/services of this product.
Others or I can be of help if you can detail your problem with this AVR. What is the brand, type or model? What is the...
You can avoid this in the future by providing drawings for customer's approval prior to ordering of major components and manufacturing (I thought this is a standard practice here in the U.S.?). Of course this will incur overhead cost but the bottom line is better product and protection against...
I think the problem is sizing/selecting a new voltage regulator. Have you tried looking at www.basler.com?
While waiting, why not try to contact the generator manufacturer or other manufacturers of similar equipment? You will definitely get a better answer from them and may even provide you...
1. Get the static exciter field resistance.
2. Run the unit at rated speed.
3. Get the no-load excitation voltage by applying dc voltage (from a battery) gradually to the static exciter field until you get the rated output of 2400Vac.
4. Compute the excitation current at no-load based on your...
I had a similar project paralleling two different diesel generators with three steam-turbine driven generators. You said that the governors and voltage regulators of the turbine-gen will be upgraded/retro-fitted and the diesel-gen is new. The most important that you should consider here is the...
