STC Series Three-Phase A.C.Synchronous Generator

These three phase generators are designed for a wide variety of electric power requirements in towns and villages, farming, construction, mountain districts and pasture lands. It can also be used as a standby power source for emergency purposes. These generators are of drip-proof construction with a rotary field and harmonic excitation system that allows for ease of operation and simple maintenance. The generators are of three-phase four-wire type making use of a star connection with a single neutral point. The rated line voltage is 400V with separate phase voltage of 230V. Frequency of 50Hz with a power factor of 0.8( lag) . This generator can also be supplied at 60Hz and other voltage' s according to your requirements. They can be coupled with a prime mover directly or through a V-belt making clockwise or counter-clockwise continuous rotation at the rated speed. When the revolution of the prime mover changes by 3% and load varies in the range of 0� 100% cos¦ Õ 1.0� 1.8 these units provide a constant voltage. After a sudden change ( increase of decrease) of load, the generators will soon return to their normal working state.
