Measuring the operate and time limit for set values

Operation mode 3I
Procedure
1. Set the polarizing voltage to 1.2 ·
current to the set characteristic angle (
voltage.
Take setting
2. Inject current until the function picks up, and make sure that the operate current of the
set directional element is equal to the
The I Dir (3I
3. Assume that φ´ is the phase angle between injected voltage (3U
´ =
the function operates.
4. Compare the result with the set value and make sure that the new injected 3I
equal to the setting
Take the set characteristic into consideration, see Figure
5. Measure the operate time of the timer by injecting a current two times the set
value and the polarizing voltage 1.2 ·

IECEQUATION2402 V2 EN-US
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
8. Continue to test another function or complete the test by setting the test mode to
