The relay features an integrated disturbance recorder which continuously captures

the curve forms of the voltages as well as the status of both internal signals and the

external digital input signals and stores these in the memory.

Triggering of the recorder generates an event code. After the recorder has been

triggered, it continues to record data for a pre-defined post-triggering time. An

asterisk is shown on the LCD on completion of the recording. The status of the

recording can also be viewed using SPA parameter V246.

As soon as the recorder has been triggered and the recording has finished, the

recording can be uploaded and analyzed by means of a PC provided with a special

program.

5.1.11.2. Disturbance recorder data

One recording contains data from the four analog channels and up to eight digital

channels. The analog channels, whose data is stored either as RMS curves or as

momentary measured values, are the voltages measured by the relay. The digital

channels, referred to as digital signals, are start and trip signals from the protection

stages and the digital input signals linked to the relay.

The user can select up to eight digital signals to be recorded. If more than eight

signals are selected, the first eight signals are stored, beginning with the internal

signals followed by the digital input signals.

The digital signals to be stored are selected with parameters V238 and V243; see

Table 5.1.17.-5 and Table 5.1.17.-6.

The recording length varies according to the selected sampling frequency. The RMS

curve is recorded by selecting the sampling frequency to be the same as the nominal

frequency of the relay. The sampling frequency is selected with SPA parameter M15;

see the table below for details.
