Construction of vector diagrams

Lecture




φn = φN = 0 coincide with the origin. It is convenient to direct the phase voltage vector in the opposite direction to the direction of the voltage.

To find   Construction of vector diagrams necessary to   Construction of vector diagrams with the opposite sign add   Construction of vector diagrams .
Connect A with B, we get a vector   Construction of vector diagrams etc. for   Construction of vector diagrams and   Construction of vector diagrams .
Phase voltage vectors form a star.
Linear stress vectors form an equilateral triangle.

The sum of the line voltages is always 0

  Construction of vector diagrams

The triangle is equilateral, therefore, i.e.
