Load Reference Arrow System
In general, the “Load Reference Arrow System” is used for loads (consumed energy) and the “Generator
Reference System” is used for generators (generated energy).
Within the HighPROTEC the “Load Reference Arrow System” is used exclusively.
This applies to directions and phase angles. The phase angle is defined as the angle from the current phasor to
the voltage phasor. Current and voltage arrows are to be counted positive in the direction of the arrow. The
advantage of determining the load reference arrow system as the standard is that it is not necessary to change
the direction of the current arrow if there is a transition from motor to generator.
