Electric generator (STC series three-phase)

STC series three-phase alternator/generators are to be used in town, the countryside, worksites,mountain and pasture lands as a electric powersource for lighting purpose. It can also be used as a reserved power source for emergent case.
The generators are of drip-proof with rotary field type and harmonic excitation system, making use of the star connection with neutral point. The rated line voltage is 400V, phase voltage is 230V, frequency is 50HZ, power factor is 0.8(lag). We can provide the generator with 60HZ and the other voltage according to request.
They can be coupled with a prime mover directly or through V-belt, rotating right or reverse continuously at the rated speed. When the revolution slip of prime mover is 3% and the load varies in the range of 0-100%, cos j 1.0-0.8, the constant voltage keeps excellent. After a sudden change(increase or decrease) of load, the generators will soon return to their normal working state. The generator can directly start and unloaded squirrel cage induction motor without any starting devices.
