Testing functionality by secondary injection
3.
Increase the injected voltage to about 110% of the setting ( 3U0 ) operating voltage.
4.
Activate the CRL binary input.
5.
Check that the ECHO, CS and TRWEI appear on the corresponding binary output or on the
local HMI.
6.
Reset the CRL binary input.
7.
Activate the BLOCK binary input.
8.
Activate the CRL binary input.
9.
Reset the CRL and BLOCK binary input.
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.
13.
Abruptly reverse the current to 65° lagging the voltage to operate the forward directional
element.
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.

Completing the test
Continue to test another function or end the test by changing the TESTMODE setting to Off. Restore
connections and settings to the original values, if changed for testing purposes.

Tripping logic, common 3-phase output SMPPTRC
Prepare the IED for verification of settings outlined in Section
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.
