By adding 90º to the angles shown on the table, the represented units 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 unit, 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
We would obtain a mixed Protection Between figure (d) and figure (e).
b) SETPOINTS
Table 5–67: 32 UNIT SETPOINTS
The snapshot event setpoint enables or disables the snapshot event generation for this unit.
Function: Enables or disables the directional element.
Blk Time After Close: In seconds. This setpoints allow to block the 32 element during the time specified in
the setpoint after the breaker switches from OPEN to CLOSED.
Dir Power Angle (1-2) (RCA): This setpoint specifies the relay characteristic angle (RCA) for the directional power
unit. This setpoint provides ability to respond to the function in any direction defined
(active forward power, active low forward power, etc.)
