Drag indicator

The drag indicator function records the 3 highest average values over a defined period (time base). The measurement device determines drag indicators for currents, active and apparent powers.

Time base

The measurement device calculates the average values from the measured values over this period. The 3 highest average values are saved with a time stamp.

Synchronization mode

The synchronization determines the start time for the time base.

You can optionally start the synchronization via:

• The internal device clock (setting Internal synchronization only).

• A parameter setting (setting Synchronization via Modbus).

• Digital input 3 (setting Drag indicator synchronization).

Capture time (seconds)

The Capture time describes the time window in which an incoming pulse synchronizes the time instant.

If the device receives a pulse outside the capture time, the calculated average values are deleted and the time is reset.
