Check in the operational or spontaneous annunciations that there is not any information on inconsistencies.
The matching factors of all measured value inputs are indicated in the operational annunciations. It is recom-
mended to check these factors even if none of the above mentioned alarms is present. The indicated factors
are:
generally, the ratio of the rated current/voltage of the side referred to the rated current/voltage of the
instrument transformers at the measuring locations;
for differential protection, the ratio of the rated current of the protected object referred to the rated
current of the current transformers at the measuring locations;
for restricted earth fault protection, the ratio of the rated current of the assigned side of the protected
object referred to the rated current of the starpoint current transformer.
None of these factors should be greater than 8 or smaller than 0.125. Otherwise, the risk of higher measuring
errors could arise. If a factor is greater than 50 or smaller than 0.02, unexpected reactions of protection func-
tion may occur.
