A 118 year old photograph of the Pelzer SC hydroenectric power plant, three 875 HP turbines drive the three 750 KW, 167 RPM, 3,300 Volt GE generators which are shown.

Judging from the 167 RPM rotational velocity of the generators, the generated AC voltage would have been 16.7 cycles per second. Large electrical motors, as used in the factory, operated more efficiently with lower frequency AC voltages.

The Tucapau Power Houseturbines produced 1400 HP each, and drove the generators which ran at 400 RPM, and produced 40 CPS (Hz in modern day terminology) AC voltage, 10KV at 1200KW. (1.2 Megawatts)

Another view of one of the 750KW Pelzer GE generators can be seen in [id=279826317; this photo] and in [id=279826195; this photo], both posted by Jeffrey Kraemer on May 30, 2010..

This original setup has the power- ake-offs, and the flat leather belts to power the ancillary equipment in the building. The 750KW generator in the front, has a belt from its drive shaft, to rotate a small generator with a four-pole rotor, in the foreground. This may have been used to power the building's electrical lighting circuits directly.
