Embodiment 1
[0016] Depend on Figure 1-3 It can be seen from the illustrated embodiment that it includes a circular voltage phasor diagram board 1 with a 0°-360° phasor scale mark and a circular current phasor diagram board 2 with a 0°-360° phasor scale mark, The centers of the voltage phasor diagram 1 and the current phasor diagram 2 are connected by the rotating shaft 3; the voltage phasor diagram 1 and the current phasor diagram 2 have the same diameter, and the current phasor diagram 2 or the voltage phasor diagram located above Plate 1 is a transparent material.
[0017] The current phasor diagram 2 is located above the voltage phasor diagram 1, the current phasor diagram 2 is made of plastic, and the voltage phasor diagram 1 is made of copper.
[0018] The 0°-360° phasor scale of current phasor diagram board 2 is marked in red; the 0°-360° phasor scale of voltage phasor diagram board 1 is marked in black.
Embodiment 2
[0020] Including circular voltage phasor diagram 1 with 0°-360° phasor scale marking and circular current phasor diagram 2 with 0°-360° phasor scale marking, voltage phasor diagram 1 and The center of circle of the current phasor diagram 2 is connected by the rotating shaft 3; the diameter of the current phasor diagram 2 or the voltage phasor diagram 1 located above is smaller than the voltage phasor diagram 1 or the current phasor diagram 2 below, so that the following The 0°-360° phasor scale mark on the outer circle of the phasor diagram is not blocked by the upper phasor diagram.
[0021] The current phasor diagram 2 is located above the voltage phasor diagram 1, the current phasor diagram 2 is made of plastic, and the voltage phasor diagram 1 is made of copper.
[0022] The 0°-360° phasor scale of current phasor diagram board 2 is marked in red; the 0°-360° phasor scale of voltage phasor diagram board 1 is marked in black.
