Display of phasors and power
Information
The example shows the use of a display element for voltage and current 'phasors' with additional power bars.
The phase of 'voltageL' moves in positive sense with increasing amplitude.
Inductive current (blue) is behind, capacitive ahead of voltage (red).
The left bar (green) displays the active power,
the right bar (violet) displays the reactive power.
An additional arrow indicates the direction of active power flow.
The example uses the dqo-representation, but is valid for abc too.
