4. Compare the result with the set value and make sure that the new injected 3I

cos φ is equal to the setting INcosPhiPU..
Take the set characteristic into consideration, see Figure 55 and Figure 56.
5. Measure the trip 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
UNREL 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.
