GTEngineer... just punch-in the number I produced above, ar the search Icon ! Phil

GTEngineer... I suggest a search for Thread # 1239015160, "Boiler Flame Failure" ! It discusses the catastrophic explosion of a 16-burner boiler with 32-flame detectors, because of the wrong logic ! Phil

GTEngineer... Sorry for the confusion ! The original Control.com site used 12-digit numbered threads. Using the Magnifying-glass icon, reveals 141 threads ! Unfortunately my "library" lists them using the original 12-digits ! Perhaps I can help if you provide the logic you seek. For example... 1...

GTEngineer... There are over 100 threads Flame-Detection files in the original Control.com, but I'm at a loss to explain how to extract them! Regards, Phil Corso

Correction: Actually Peak-Voltage to ground is about 560 V!

Hans... as EE's we both recognize that the terminal connections are typical for dual-voltage motors. But, we certainly don't know the Mfg's motive for not labeling it as such, and for listing only 220V (with 'CE' Tag) on the nameplate. Here's my theory: "We" are technically aware that if there...

Hans (please excuse the Informality)... are the 3 supply-leads connected to the top or bottom terminals? My conclusions: 1) although the links provided are typical of a dual-voltage motor application, there is no visible evidence it could be operated @ 400V. 2) Also, you don't know if 2 of the...

Abdouzita... thanks for schematic. 1) How about the environment, cold, hot, steamy? 2) Refinery, Chem plant, other hazardous process? 3) Are prevailing wind from another process facility? 4) Are failures appearing in same area of plant? 5) Are failures occurring in same Instrument enclosure...

u1v1w1... I suggest you look at IDEC's RTE series of timing relays! Regard, Phil Corso

"abdouzita... How about a schematic diagram or sketch of the installation? Phil Corso

KP... 1) Can you provide photo of Motor's nameplate! 2) Is wiring diagram your measurement by Ohm-meter test? 3) Or by visual observation? 4) What is motor application? Phil Corso

An aside... Once worked on an HRSG in a country where the plant owner tried to get away with paying taxes by calling the facility a Flue-Gas Cooler! Phil Corso

Carlos... Congratulations... Saw your facilities on You-Tube. Interesting fact... largest in Europe, plus includes a pumped-storage plant! I'm surprised you can't get advice from Alsthom! Phil Corso

Carlos... the Hydro-Vision study is available on the Web, as a PDF file ! Phil Corso

Carlos… is your project associated with our Government’s Hydropower Vision study? Following is a quote from José Zayas Director, Wind and Water Power Technologies, USA Dept of Energy: “Hydropower Vision highlights the great potential of untapped hydropower resources across the United States...

Carlos... I suggest contacting Hydro-Service organizations.

Carlos... While not an expert, I do teach a Renewable Energy course in which The Pelton is discussed with some detail. As you stated the energy of the water-jet impinging on a number of buckets mounted on the periphery of a wheel is eventually converted to electrical energy! Simple, but if the...

Tusar, The Probabilistic-Risk-Assessment for SIS is a 3-state analysis considering overt and covert failure of components. Did I also forward EPRI Study # 5416, having to do with Nuclear Plant Turbine Protection Evaluation? That study concluded 2003, with component failure diagnostics, was...
