Function of the Energy trip unit
3.3 Measurement function
- Synchronised integration period (Sync. Bus)
Fixed integration interval
The calculation intervals are consecutive.
A new average value is calculated at the end of the interval.

Fixed integration interval
The duration of interval T can be configured between 5 and 60 minutes in
increments of 1 minute.
Sliding integration interval
The calculation intervals are consecutive.
A new average value is produced every minute.

Sliding integration interval
The duration of interval T can be configured between 5 and 60 minutes in
increments of 1 minute.
Synchronised integration interval
When the first synchronisation pulse is received, a first averaged value calculation
is initialised. For each new pulse, the integration in progress is stopped and the
average value available is updated. At the same time, a new calculation is initialised.
The time interval between two synchronisation pulses must be between 1 and
60 minutes. If the interval exceeds 60 minutes, integration of the measurement
stops and the measurements up to the next synchronisation pulse are not taken
into account.
