The following table shows the SMIN and angle values that must be used for some typical applications:
Table 5-61: Directional power element
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 can 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
We would obtain a mixed Protection Between figure (d) and figure (e).
Settings
Table 5-62: 32 element settings
The snapshot event setting enables or disables the snapshot event generation for this element.
Function:
Enables or disables the directional element.
Blk Time After Close:
In seconds. This settings allow to block the element 32 during the time specified in the
setting after the breaker switches from OPEN to CLOSED.
Dir Power Angle (1-2) (RCA):
This setting specifies the relay characteristic angle (RCA) for the directional power
element. This setting provides ability to respond to the function in any direction
defined (active forward power, active low forward power, etc.)
