RPV311
Distributed Multifunction Fault Recorder
Chapter 6: Records
This chapter details all types of registers created by the RPV311.
1 Continuous and Triggered Fault Records
Fault records can be created in the following ways:

Continuously:
Measurements are continuously recorded. A new record is available each 10
minutes. The record size depends on the number of derived measurements selected
by the user (limited to 16).

By trigger:
The fault recorder can be triggered by a Boolean equation, by a cross-trigger signal
of another recorder or by a manual trigger using the Web Interface.
Continuous and triggered fault records share the same mass storage area.
1.1 Recorded Values
The following values are recorded by the fault recorder:

Voltage waveform of all voltage circuits (A, B, C, and N);

Current waveform of all current circuits (A, B, C, and N);

Transducer waveform of all transducer channels;

Digital channels (state of digital inputs and binary GOOSE messages).
1.2 Recording Times by Trigger
Once triggered, the following parameters are considered by the fault recorder:

0 … 5 s
