General Interrogation
The present condition of the SIPROTEC 4 device can be retrieved via DIGSI by viewing the contents of the
General Interrogation. It shows all indications that are subject to general interrogation with their current
value.
Statistics
Counting includes the number of trips initiated by 7VK61, the accumulated breaking currents resulting from
trips initiated by protection functions, the number of close commands initiated by the auto-reclosure function.
Functional Description
Counters and Memories
The counters and memories of the statistics are saved by the device. Therefore, the information will not get
lost in case the auxiliary voltage supply fails. The counters, however, can be reset to zero or to any value
within the setting range.
Switching statistics can be viewed on the LCD of the device, or on a PC running DIGSI and connected to the
operating or service interface.
A password is not required to read switching statistics; however, a password is required to change or delete
the statistics. For more information see the SIPROTEC 4 System Description.
Number of trips
The number of trips initiated by the device 7VK61 is counted. If the device is capable of single-pole tripping, a
separate counter for each circuit breaker pole is provided.
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
reclosure 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.
Setting Notes
Reading/Setting/Resetting
The SIPROTEC 4 System Description describes how to read out the statistical counters via the device front
panel or DIGSI. Setting or resetting of these statistical counters takes place under the menu item INDICA-
TIONS -> STATISTICS by overwriting the counter values displayed.
