Recording Times by Trigger

RPV311-TM-EN-7
Derived measurements are continuously recorded. A new record is created at each
hour rollover. The record size depends on the number of derived measurements
selected by the user (limited to 64).

By trigger:
The disturbance recorder can be triggered by a Boolean equation, by a cross-trigger
signal of another recorder, by a manual trigger using the Web Interface, or by the
triggering of the fault recorder. It is possible to select the derived quantity of
triggered disturbance records. If the quantities are not manually selected, the record
will consist of all the quantities available for measurement. The record size depends
of the number of derived measurements selected by the user.
Continuous and triggered disturbance records share the same mass storage area.
The following values are recorded by the continuous and triggered disturbance
recorders:

RMS value of voltage and current circuits;

Voltage and current phasors;

Frequency of voltage circuits;

Positive sequence of voltage and current circuits;

Negative sequence of voltage and current circuits;

Imbalance of voltage and current circuits;

Total harmonic distortion of voltage and current circuits;

Apparent combined power of power circuits;

Apparent fundamental power of power circuits;

Active fundamental power of power circuits;

Reactive fundamental power of power circuits;

Digital channels (state of digital inputs and binary GOOSE messages).
Once triggered, the following parameters are considered by the disturbance
recorder:
