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
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
currents, pickup durations and time stamp, for instance. Additionally, information
on the number of pickups of the elements, trips and auto-reclose shots 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 of the elements.
The number of trips and auto-reclose shots 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
and the number of auto-reclose shots by entering the value 2 into
parameter
V166
.
The relay collects data during fault conditions. When all pickup or thermal alarm
signals have been reset or an 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.
