EMFA ELECTRICAL CO,,LTD
THREE-PHASE A. C.SYNCHRDNDUSGENERATORS
^1
The generators are widely used in town, countryside, worksites, mountains and pasture districts as electric
powersource forlighting. They can also be used as reserved powersourceforemergency.
These series generators are of drip-poof with rotary fie Id type aid adopt harmonic excitation system, easy
operation and maintenance.
The generators are three-phase, four-wire type, adopted bystar connection with neutral point. The rated
line voltage is 400V, phase voltage is230V, frequency is50Hz, Dower factor 0.8 (lag). We can provide 60Hz
and othervoltagesgenerator accordingto the'customer' s request.
Theycan be coupled with a prime mover directly or through V-balt making right or reverse continuous rotation
at the rated speed whenthe revolution slip of prime mover is3%and load varies within the range of
O~1OO%cos0=O.8~l .OThey give good constantvoltage.
The generators offer constantvoltage when sudden change (increase or decrease) of load, the generator will
soon return to their normal working rate. At the same time, the generator can directly start an unloaded
squirrel cage induction motorwithout any starting devices.
