Commissioning manual
Testing functionality by secondary injection
can be controlled. During the test, the analog outputs of active and reactive power
shall be monitored.
1. Connect the test set for injection of voltage and current corresponding to the
mode to be used in the application. If a three-phase test set is available this
could be used for all the modes. If a single-phase current/voltage test set is
available the test set should be connected to a selected input for one-phase
current and voltage.

2. Adjust the injected current and voltage to the set values in % of IBase and
UBase (converted to secondary current and voltage). The angle between the
injected current and voltage shall be set equal to the set direction Angle1,
angle for stage 1 (equal to 0° for low forward power protection and equal to
