STC SSERIES THREE-PHASE A.C. SYNCHRONOUS GENERATOR

 

The generators are widely used in town, countryside, worksites, mountain and pasture districts as electric power source for lighting purpose, they can also be used as reserved power source for emergency.

The series generators are of drip-poof with rotary field type and adopt harmonic excitation system,easy operation and maintenance.

The generators are ther-phase,four-wire type, adopted star connection with neutral point, The rated line voltage is 400V, phase voltage 230V, frequency 50Hz,power factor 0.8(lag).we can provide 60Hz and other voltage generators according to the customer's request.

They can be coupled with a prime mover directly or through V-belt making right or revese continuous rotation at the rated speed when the revolution slip of prime mover is 3% and load varies within the range of 0~100%cosX=0.8~1.0 they give good constunr voltage.

The generators offer consranr voltage when sudden change(increase or decrease) of load,the generator will soon return to their normal working state in the same time,the generator can directly start an unloaded squirrel cage induction motor without any starting device.
