Transformation Ratio - Active
When using an interposing transformer, of if there is multiple looping of the main current
cables through the current/voltage measuring module, you can enter the transformation ratio
of the interposing transformer.
Activate the checkbox if you wish to use this option. The parameterized set current thus
continues to correspond the actual nominal motor current and does not have to be
converted. The transformation ratio is calculated from the ratio between nominal motor
current [A] and measuring current [A] or any multiple of this ratio.
Transformation Ratio - Primary
Enter the primary current here, with the "Transformation ratio - active" checkbox activated.
Range: 0 - 8191,875.
Transformation Ratio - Secondary
Enter the secondary current here, with the "Transformation ratio - active" checkbox
activated.
Range: 0 - 15.
