Compare the result with the expected value.
The expected value depends on whether definite or inverse time was selected.

1.
Set the polarizing voltage to 1.2 ·
UNRel>
and set the phase angle between
voltage and current to the set characteristic angle (
RCADir
). Note that the current
lagging the voltage.
2.
Inject current until the function picks up, and make sure that the operate current
is equal to the
INDir>
setting for the set directional element.
Note that for operation, both the injected current and voltage
must be greater than the set values
INRel>
and
UNRel>
respectively.
The function activates the START and STDIRIN output.
