14. EVENT RECORDER – REPORTS
Operation of the
u REG
protective device is associated with certain events which must be
considered by operating staff. Attributes, conditions and circumstance of such events result
from
the definition of the application software and the assigned indices . The four tabs are:

situations resulting from device operating as a protective solution (associated directly
with behavior of the transformer, busbars, circuits, etc., and execution of protective
criteria);

situations affecting recognition of criterial situations (e.g. changing settings and fixing
settings);

various circumstances inside the protection, determining its instantaneous efficiency
(inefficiency) as well as those which are alarming as regards continued efficiency in the
immediate future.
All extraordinary situations observed during operation are saved by
u REG
in the event
recorder as the so-called reports . Reports are collected in the caching repository in the order
of creation.
The report repository of
u REG
can collect up to 1024 reports.
All reports are saved in a non-volatile repository – their content is stored by the period of
auxiliary voltage dip.
Ongoing readout of event reports from the device should be performed by the supervisory
system, e.g. a substation hub.
Previewing recorded reports is possible by means of keyboard operations using the local LCD
screen or remotely via readout commands sent from the computer.
14.1. REPORTS – PREVIEW THOUGH u REG MENU
The reports are accessible on the main level [ident 6 ‘ Reports ’] in the menu structure of the
LCD screen. Report presentation is subject to a rule stating that each step into the report
structure results in automatic report renumbering. With this solution,
reports are always
presented from the earliest report , which is assigned with the number 00.

The reports shown on the alphanumeric display of the unit equipped with an NV panel
present:

report no.;

event code (as a hexadecimal protocol index, e.g. DNP-3);

time marker given as date and time when recorded (for milliseconds);

microsecond extension of the time marker (accuracy up to 100 us).
Example:
02 000E 11.06.01
11:47:30.888 1
→ report no. 2, code 000Eh = 14, date 2011.06.01, hour 11:47:30.888 + 100us.
