Basics of electrical engineering Theme Three-phase alternating current Issue 4
On the rotor of the two pole generator, three windings with the same number of turns are placed, which are shifted one hundred and twenty degrees from each other. When the rotor is rotated, a sinusoidal EMF is induced in the winding. The values ​​and periods of EMF in each winding are the same. The only difference is that their zero and amplitude values ​​do not occur simultaneously.
Each winding of the generator is called the phase (Fa).
Star connection.
A star connection is a phase connection of consumers when the ends of these phases are connected to one point, and the beginning is connected to three linear wires.
Phase voltage is the voltage between each of the line wires and the zero wire.
The minimum voltage is the voltage between any two line wires.
Delta connection.
A triangle connection is such a connection that the end of the first phase is connected to the beginning of the second phase, the end of the second phase with the beginning of the third phase, and the end of the third phase is connected to the beginning of the first phase.
