Verifying the settings

1. Connect the test set for the injection of a three-phase current to the appropriate current
terminals of the IED.
2. If current need to be injected for a particular test, it should be done in the phase selected
by the
3. Follow the sequence for positioning the auxiliary contacts before testing:
POSCLOSE
POSOPEN
4. Test of CB contact travel time

4.2. Change the status of the auxiliary contacts such that travel time to open TTRVOP
4.3. Check that TRVTOPAL and TRVTCLAL are activated.
5. Test of CB status

When the breaker goes to open position, accumulated energy IPOWPH is calculated.
The calculated value can be seen on the output IPOWPH.
Alarm signal IPOWALPH appears when IPOWPH is greater than set
value.
Lockout signal IPOWLOPH appears if IPOWPH exceeds further to the threshold value
