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
relay control signal via a binary input, can be set to trigger the recording. Recorded
information is stored in a nonvolatile memory and can be uploaded for subsequent
fault analysis.
8.2.2.1 Recorded analog inputs
The user can map any analog signal type of the protection relay to each analog
channel of the disturbance recorder by setting the
