6. VOLTAGE AND OUTPUT FREQUENCY ON THE THREE PHASE ALTERNATORS
These alternators are designed to supply the voltage at:
⇒
400 V at 50 Hz or 480 V at 60 Hz with star/neutral connection
⇒
230 V at 50 Hz or 276 V at 60 Hz with delta connection
7. SINgLE PHASE DUTY OF THREE-PHASE ALTERNATORS
The output power in single-phase in continuous duty is approximately 65% of three-phase output
power in case of line-to-line voltage and 60% (E1S10/E1S11), 40% (E1S13) in case of phase voltage (star
connection).
8. VOLTAgE CALIBRATION AND REVOLVINg SPEED
The calibration of voltage should be carried out by qualified personnel only because of electrocution
hazard.
A checkout of the alternator’s output voltage should be carried out at the nominal revolving speed (3000 r.p.m. for the
alternators at 2 poles and 1500 r.p.m. for those at 4 poles).
The alternators are calibrated to distribute the nominal voltage.
Light deviations of the output voltage can be caused by a revolving speed which is different from the nominal one.
The output voltage changes proportionally to the revolving speed.
To correct the no-load voltage of the alternator at a specific revolving speed, it is necessary to act on the air gap of the
compound transformer as under described (see
Figure 10
).
1) Loose the tightening of two screw nuts N.
2) Modify the height of air gap considering that:
a) increasing it the voltage grows;
b) decreasing it the voltage lows down;
slight voltage variations they can be obtained with a small hammer and a screwdriver. In case the variation of
demanded voltage exceeds 5% is necessary to proceed to the replacement of the insulating thickness (T) that forms
the air gap.
3) Once regulation is effected, tighten the two screw nuts N.
ATTENTION:
for a correct operation of the alternator the voltage can not /- 5% of the plate value.
9. gENERAL NOTE
Operation in particular settings
If the alternator is going to be used within a soundproof generating set, make sure that only fresh air enters it.
This can be ensured by placing the alternator’s air inlet near the external air intake.
Moreover, remember that the quantity of air required is:
