12.4.1 Calculation of the NoLoad Limit for User-Defined
Rogowski Coils
The NoLoad limit is calculated from the product of the full-scale RMS values for
current and voltage.
For all versions of the 750-495 I/O module, the full-scale RMS value of the
voltage is 505.228 V
The full-scale RMS value is calculated from the peak value for current, which
follows from the user-defined settings for mutual inductance M and internal
resistance R
