It means that the output from the generator consists of 3 pairs of wires,
instead of one. By every pair, a sinusoidal AC voltage is applied, being 1/3
of a cycle (120 deg) delayed from the others.

By the sake of simplicity, a wire from every pair is connected to the others,
thus making a reference point, connected to the metallic airframe. This means
that 3 wires (the 3 phases) appear from the generator.
