Take setting RCAComp into consideration if not equal to 0.
2.
Measure that the operate current of the set directional element is equal to the
INcosPhiPU setting.
The I Dir (I
cos(Angle)) function activates the BFI_3P and STDIRIN output.
0
Measure with angles j = RCADir +/- 45° that the measuring element operates

cos (RCADir - j) = I
when I
0
4.
Compare the result with the set value.
Take the set characteristic into consideration, see figure
5.
Measure the operate time of the timer by injecting a current two times the set
INcosPhiPU value and the polarizing voltage 1.2 · VNRelPU.

6.
Compare the result with the expected value.
The expected value depends on whether definite or inverse time was selected.
7.
Set the polarizing voltage to zero and increase until the boolean output signal
VNREL is activated, which is visible in the Application Configuration in
PCM600 when the IED is in online mode. Compare the voltage with the set value
VNRelPU.
8.
Continue to test another function or complete the test by setting the test mode to
Disabled.
