The figure resulting from the measurement of the winding
ground resistance must be greater than 1MΩ.
If the figure is lower than the above, the windings must
be properly dried. This can be done by directing a jet of
hot air of about 50-60°C into the air inlets or outlets of
the generator, or by electrically connecting the stator
windings and subjecting them to voltage by means of a
DC power supply. The amount of current in the windings
depends on the size of the generator, although it should
be set according to the nominal values indicated on the
plate.

At regular intervals, we recommend checking that the
alternator is running smoothly without any abnormal
noise or vibration. Such phenomena could indicate
damage to the bearings.
It should be noted that the alternator itself does not
exhibit any particular vibration since the rotating parts
are perfectly balanced. Provided that the rotor balancing
has not been altered and the rotor bearings have not been
damaged, vibrations of the generator set may occur due
to the alignment of the couplings, the stresses on the
heat engine or the vibration mounts.
We also recommend checking the performance data,
which should be consistent with the data on the generator
plate.
