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 7SD610 the protection communication is registered in statistics. The transmission
times of the information between the devices via interfaces (send and receive) are
measured continuously. The values are kept stored in the statistics folder. The avail-
ability 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 interface are regularly measured and indicated as long as GPS
synchronization is intact.
2.17.3.2 Information List
2.17.4 Measurement During Operation
2.17.4.1 Function Description
A series of measured values and the values derived from them are available for on-
site retrieval or for data transfer.
A precondition for the correct display of primary and percentage values is the complete
and correct entry of the nominal values of the instrument transformers and the power
system as well as the transformation ratio of the current and voltage transformers in
the earth paths.
