10. Inject the polarizing voltage 3U0 to about 110% of the setting (3U0>) and adjust
the phase angle between the voltage and current to (180°- AnglRCA) setting, the
current leads the voltage.
11. Inject current in one phase to about 110% of the set operate current (IN>Dir ).
12. Activate the CRL binary input.
No ECHO and TRWEI should appear.
13. Abruptly reverse the current to 65° lagging the voltage to operate the forward
directional element.
No ECHO and TRWEI should appear.
14. Switch the current off and check that the ECHO, CS and TRWEI appear on the
corresponding binary output during 200ms after resetting the directional
element. If EF4PTOC also operates in forward direction, CS should be obtained.
15. Switch the polarizing voltage off and reset the CRL binary input.
10.10.5.3 Completing the test
Continue to test another function or end the test by changing the TestMode setting to
Off. Restore connections and settings to their original values, if they were changed for
testing purposes.

10.11.1 Tripping logic, common 3-phase output SMPPTRC
Prepare the IED for verification of settings outlined in section
"Preparing the IED to
verify settings".
This function is functionality tested together with other protection functions (line
differential protection,earth-fault overcurrent protection, and so on) within the IED. It
is recommended that the function is tested together with the autorecloser function,
when built into the IED or when a separate external unit is used for reclosing purposes.
The instances of SMPPTRC are identical except for the name of the function block
SMPPTRC. The testing is preferably done in conjunction with the protection system
and autoreclosing function.
