Prepare the IED for verification of settings outlined in Section "Preparing the IED to
verify settings".
13.4.6.1 Verifying the settings
SEMOD158873-39 v3
The test is done by means of injection of three phase current and three phase voltage
from a modern test device. This test device shall be able to give voltage and current
corresponding to the set apparent impedance.
1. Feed the IED with current and voltage corresponding to the apparent impedance:
Test #1, as shown in figure
50. Read the analog outputs for R and X and check
