STC Series Three-Phase
* STC Generators are to be used in town, the countryside, worksides, mountain
and pasture lands as a electric power source for lighting purpose,
* it can also be used as a reserved power source for emergent case.
* The generators are of drip-poof with rotary field type and with the adoption of harmonic
excitation system, that allow your easy operation and simple maintenance.
* The generators are of three-phase four-wire type, making use of star connection
with neutral point.
* The rated line voltage is 400V. Phase voltage 230V. Frequency 50Hz, power factor 0.8(lag).
* It can provide 60Hz and the other voltage's generator according to necessity.
* They can be coupled with a prime mover directly or through V-belt making right or reverse
continuous rotation at the rated speed. When the revolution slip of prime mover is 3% and
load varies in the range of 0-100% cosθ 1.0-0.8 the give food constant voltage.
* After sudden change (increase or decrease) of load.
* The generators will soon return to their normal working state.
* Without any starting devices the generator can directly start an unloaded squirrel cage
