Generator Nameplate 1

[VTer]

Does anyone know what RVFL stands for in Generator Nameplate "EXC. FLD AMPS-RVFL".

"Throughout space there is energy. Is this energy static or kinetic! If static our hopes are in vain; if kinetic ù and this we know it is, for certain ù then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature". û Nikola Tesla

I have an old Ideal tech guide that says it means "at Rated Voltage Full Load".

Who's generator is it, may help you get a more definitive answer.

Thank you! It is an old GE unit.

In context I think Mike L's explanation makes perfect sense because the field current required to raise nominal voltage is dependent on the load connected to the main terminals. LPS Mike.

Thank you Scotty!

I looked thru some of the old GE info I have, didn't find anything but most of the stuff I have is for units smaller than 1MW.

Just about every generator nameplate I run across when it lists field volts and field amps it is at nominal voltage with generator at full kVA output.

Hope that helps, MikeL.

I haven't seen RVFL, but it makes a lot of sense.
If a replacement exciter and/or voltage regulator can't supply the rated current and voltage then the alternator will not be able to produce full rated output.

What is the Generator S/N? I just asked Generator Engr and said that it is Exciter Field Amps Volts Full Load

going to double check on the R because typical nomenclature is
IFFL (amps field full load) or VFFL (volts field full load)
R is usually resistance
