Parameter Description
B-width Filter bandwidth for frequency selective measurement. Only available for
measurement mode Freq. sel. filter.
Possible values: 3Hz to 20Hz. Default: 6Hz
Depending on the filter bandwidth selected, the measurement time can differ
considerably. The typical time needed for a frequency selective measurement
depends on the filter bandwidth as follows:
Filter bandwidth
3Hz
6Hz
Load Only available for AC signal output.
Setting the Load parameter to "on" and specifying the winding resistance and the
unsaturated inductance in the fields R and L will prevent saturation of the connected
CT.
The output generator of CT Analyzer then keeps the DC part of the output current at
zero using a current regulator.
Possible values: On or Off. Default: Off
R, L Only available if Load is set to "on".
Winding resistance (R) and unsaturated inductance (L) of the CT, used by the internal
output regulator to prevent saturation of the connected CT (see "Load" above).
Possible values: 0 to 1000
Default: 1.00
If these values are not set correctly for the connected CT, the CT will saturate sooner
or later, depending on the inaccuracy of the values used.
