For trip circuit supervision the number of binary inputs was set incor-
rectly
In the operational or spontaneous annunciations also check if there are any fault an-
nunciations from the device.
The matching factors of all measured value inputs are indicated in the operational an-
nunciations. It is recommended to check these factors even if none of the above men-
tioned alarms is present. The indicated factors are:
• generally, the ratio of the rated current/voltage of the side referred to the rated cur-
rent/voltage of the instrument transformers at the measuring locations;
• for differential protection, the ratio of the rated current of the protected object re-
ferred 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 function may occur.
