THREE PHASE ALTERNATOR HEADS
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 415v 50Hz with separate phase voltage of 230V. Frequency of 50Hz with a power factor of 0.8(lag).
They can be coupled with a prime mover directly or by various belt/pulley configurations. When the revolution of the prime mover changes by 3% and load varies in the range of 0¡ª100% cos|1.0 ¡ª1.8 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.
