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)
Stage 1 Tap
Dir Power Angle 2(RCA)
Stage 2 Tap
