Verifying the settings

Preconditions
The following output signal shall be configured to binary output available: ZOUT, measured
impedance within outer impedance boundary.
1. Keep the measured current as close as possible to its rated value or lower. Keep it
constant during the test, but ensure that it is higher than the set minimum operating
current.
2. Ensure that the maximum continuous current to the IED does not exceed four times its
rated value, if the measurement of the operating characteristics runs under constant
voltage conditions.
3. Make the necessary connections and settings of the test equipment for test of point 1
according to figure 28.
