GENERATING OF HIGH ALTERNATING VOLTAGE 1. A multi-phase induction generator has more poles, and therefore a lower synchronous speed. BHT is dedicated to the research, design and manufacturing of high-voltage test equipment. AC generators have no commutator and can, therefore, be built in very large units to run at high speeds producing high voltages (as high as 11,000 volts), so that the construction and operating cost per kW is low, whereas dc generator capacities and voltages are limited to comparatively low values. Here we see an AC sine wave and we see that it is constantly changing going negative or going positive and then negative.
