The device also checks the matching factors between the rated currents of the CT’s and the operational
currents of the protected object(s) as processed by the protection functions. If very high deviations combined
with sensitive protection settings are discovered an alarm is output which also indicates the suspicious setting
address(es).
In the operational or spontaneous annunciations also check if there are any fault annunciations from the
device.
