Phasor diagram
The phasor diagram visualizes the phase angles between the currents and the voltages and thus depicts the asymmetries of the fundamentals.
In the middle - new Phasor diagram with Phase angle U-I values (no currents measured)
- The following aspects were taken into account for the visualization:
- The voltage arrow U1 is always at the 3 o'clock position with its zero phase angle φ1N = 0°
- Phase angles U-U: From the 3 o'clock position, positive zero phase angles are rotated counterclockwise and negative zero phase angles clockwise.
- Phase angles U-I: Starting from the respective voltage arrow, positive angles (characterise inductive currents) are rotated clockwise, negative angles (characterise capacitive currents) counterclockwise.
- The radius of the circle corresponds to the average conductor voltage UsysLN
- The length of the individual voltage arrows is proportional to UsysLN according to their values
- The length of the current arrow that represents the highest current value corresponds to 80 % of UsysLN
- The length of the other current arrows is proportional to the longest current arrow according to their values
Note: A static reference situation (with U1 = 0 & Time = 0) is always shown in the phasor diagram. The arrows in the phasor diagram would rotate counterclockwise over time, regardless of the direction of the rotary field, if the mapping were dynamic.
