How It Works
"A hydraulic turbine converts the energy of flowing water into mechanical energy.
A hydroelectric generator converts this mechanical energy into electricity. The operation
of a generator is based on the principles discovered by Faraday. He found that when
a magnet is moved past a conductor, it causes electricity to flow. In a large generator,
electromagnets are made by circulating direct current through loops of wire wound
around stacks of magnetic steel laminations. These are called field poles, and are
mounted on the perimeter of the rotor. The rotor is attached to the turbine shaft,
and rotates at a fixed speed. When the rotor turns, it causes the field poles (the
electromagnets) to move past the conductors mounted in the stator. This, in turn,
causes electricity to flow and a voltage to develop at the generator output terminals."
The Generator in the photo to the left was made by General Electric Co limited from
Peterborough, Toronto,Ontario, Canada.
The data tags on the generator in the foreground (see below) show the specifications
for the generator.
The lower blue plate shows that the generator was rewound by Thompson Electrical
Works Limited, Montreal, Quebec, Canada in 1965 and produces:-
