Determining actual current and voltage signals phase-shift for any phases in three=phase network e.g. for power factor control - determining reference coordinates for vector diagram from vector differences when switching on and off pure resistive or inductive or mixed loads

摘要

The method involves switching on and/or off at least one purely capacitive or purely inductive, purely resistive load or a mixed load of defined phase-shift. The vector differences measured when switching on or off are then used as reference coordinates in a vector diagram.
