Settings for Rogowski coils
If you are using Rogowski coils with the Rogowski version, user scaling cannot
be enabled. Thus, the transformation ratio is always 1:1. Otherwise, incorrect
measured values will result.
•
For “Min./Max. Values”, enter the undervoltage limit, the overvoltage
threshold and the undercurrent threshold. If this value is not reached or is
exceeded, an error bit is set in the status byte of the process image and a
red error LED is enabled.
Also specify whether or not the measured min./max values for current,
voltage, power and frequency should be reset automatically after a certain
amount of time. If they should, specify the reset interval.
•
You can make 2 general settings: the interval setting for the calculation of
the arithmetic mean (in s) and the interval setting for peak value
measurement (in half-waves).
