Figures (a, b, c, d, e, f) below shows settings for different power applications.
Figure 5–14: DIRECTIONAL POWER ELEMENT SAMPLE APPLICATIONS
By adding 90º to the angles shown on figures a, b, c and d, the represented elements would be similar but with Reactive
Power instead of Active Power.
Any other angle would provide a mixed Protection Between Active and Reactive power.
A different angle selection for Stage 1 and Stage 2 could provide in a single element, a Reactive and Active power
limitation. For example, using the following values:
Dir Power Angle 1(RCA) 0º
Stage 1 Tap 0
Dir Power Angle 2(RCA) 90º
Stage 2 Tap 0
