Testing functionality by secondary injection
Take the set characteristic into consideration, see Figure
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.
