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 pickup or trip signals of the relay stages, or external blocking or control
signals. Binary relay signals, such as a protection pickup or trip signal, or an external relay
control signal via a binary input, can be set to trigger the recording.Recorded information
is stored in a non-volatile memory and can be uploaded for subsequent fault analysis.
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 Channel selection parameter of the corresponding
