No output on generator
No output on generator
(OP)
I have a 5 KVA, 1500 RPM 220 Volt generator manufactured by a company called Brush.
It has not been used for a number of years; there is little or no output the wiring seems to be ok.
Any ideas please keep it simple for a simple mind!

Other than that, what is the excitation arrangement? There should be a DC supply to the field, probably via slip rings but possibly through a smaller machine mounted on the main shaft which is fed DC to the armature and produces a 3-phase AC supply which is rectifed on the shaft to feed the field.

First, check circuit breakers, the check the condition of the commutator. Check the brushes, if they are not touching the commutator you get no voltage or little to the load. Check the commutator it has not ran in some time this can become dirty and cause poor continuity. Next, you can check the dc exciter. These are prone to go bad especially if you have not used it in a while. Talk to you soon

(No brushes, no voltage regulator).
If so, check the capacitors, and "flash" the field by applying 12 volts DC to the load terminals of the generator when it is stopped.

iam electrical engineer waddah from palestine and i used to make maintenance to electrical diesel generators,so if your generator is with brushes and you measure between pahse ad nuetral and you have more than 5 to 10,then that means both the statore an the armature are in good conditions,then check out that you have diode bridge and chech if the diode bridge is defected if not then check the slip rings on the rotating armature and the brushes are connected and delivering electric current to the diode bridge,some times you will fand acapacitor also if that capacitor id defected you will not have electricity,that is all that you can do for your generator,hopefully i had given you the tips for checking your generator
