Triggering of the disturbance recorder is only possible if the recorder is not
already triggered.
5.1.11.5. Settings and unloading
The setting parameters for the disturbance recorder are V parameters
V236
...
V238
,
V240
...
V243
and
V246
, and M parameters
M15
,
M18
,
M20
and
M80
...
M83
.
Unloading correct information from the recorder requires that
M80
and
M83
have been set. Unloading is done by using a PC application. The uploaded
recorder data is stored in separate files defined by the comtrade® format.
5.1.11.6. Event code of the disturbance recorder
The disturbance recorder generates an event code on triggering (E31) and
clearing (E32) the recorder. The event mask is determined using SPA
parameter
V155
.
5.1.12. Recorded data of the last events (Fault summary)
The relay records up to five events. This enables the user to analyze the last
five fault conditions in the electrical power network. Each event includes the
measured voltages, pickup durations and time stamp, for instance.
Additionally, information on the number of pickups and trips is provided.
Recorded data is non-volatile by default, provided that the battery has been
inserted and is charged. A master reset, that is, clearing of targets and
memorized values and unlatching of output contacts, erases the contents of
the stored events and the number of pickups.
The number of trips is stored in the non-volatile memory
(EEPROM) and is thereby not cleared when performing a master
reset. The number of trips can be erased by entering the value 1
into parameter
V166
.
The relay collects data during fault conditions. When all pickup signals have
been reset or a element trips, the collected data and time stamp is stored as
EVENT1
and the previously stored events move one step forward. When a
sixth event is stored, the oldest event is cleared.
