Function description
Disturbance recorder
Functionality
The relay is provided with a disturbance recorder featuring up to 12 analog and 64
binary signal channels.The analog channels can be set to record either the waveform
or the trend of the currents and voltages measured.
The analog channels can be set to trigger the recording function when the measured
value falls below or exceeds the set values. The binary signal channels can be set to
start a recording either on the rising or the falling edge of the binary signal or on both.
By default, the binary channels are set to record external or internal relay signals, for
example, the start or trip signals of the relay stages, or external blocking or control
signals. Binary relay signals, such as protection start and trip signals, or an external
