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 single-pole tripping, after three-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.

2.9.2.2 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 Annunciation
-> STATISTIC by overwriting the counter values displayed.

Measurement

2.9.3.1 Functional Description

Display of Measured Values
Depending on the ordering code, connection of the device and configured protection functions, only some of
the operational measured values listed in table 2-8 may be available. Phase-to-earth voltages can only be mea-
sured if the phase-to-earth voltage inputs are connected. The displacement voltage 3 U
tiplied with √3 – if U
