Number of automatic reclosing commands
If the device is equipped with the integrated automatic reclosure, the automatic close commands are also
counted, separately for reclosure after 1-pole tripping, after 3-pole tripping as well as separately for the first re-
closure cycle and other reclosure cycles.
Interrupted currents
Furthermore, for each trip command the interrupted current for each pole is acquired, output in the trip log and
accumulated in a memory. The maximum interrupted current is stored as well. The indicated measured values
are indicated in primary values.
Transmission statistics
In 7SD5 the protection communication is registered in statistics. The delay times of the information between
the devices via interfaces (run and return) are measured steadily. The values are kept stored in the Statistics
folder. The availability of the transmission media is also reported. The availability is indicated in % / min and
% / h. This enables an evaluation of the transmission quality.
If GPS synchronization is configured, the transmission times for each direction and each protection data inter-
face are regularly measured and indicated as long as GPS synchronization is intact.
