Voltage Relay
Technical Reference Manual
The trigger signal(s) and the edge are selected with SPA parameters V236...V237
and V241...V242; see Table 5.1.17.-5 and Table 5.1.17.-6. The recorder can also be
triggered manually with SPA parameter M1.
Triggering of the disturbance recorder is only possible if the recorder is not already
triggered.

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.

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.

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
voltages, start durations and time stamp, for instance. Additionally, information on
the number of starts of the stages 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 indications and memorized values
and unlatching of output contacts, erases the contents of the stored events and the
number of starts of the stages.
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 start signals have been reset
or a stage 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.
