The following values are displayed in the Results CT Ratio card:
Use the following wiring for CT ratio measurement (example):
Figure 8-10 Wiring example for CT ratio measurement
R, L 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 1000Ω or 0 to 1000H.
Default: 1.00
Ω for R and 50.00H for L
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.
Value Description
Output Internally measured RMS current value and phase of the output
signal.
Sec RMS value of the voltage measured at input "Sec".
This input is considered as the phase reference, therefore the
phase is always 0.
Prim RMS value and phase of the voltage measured at input "Prim".
N Current ratio of the CT calculated from the voltages measured
at inputs "Sec" and "Prim".
f Frequency measured at input "Sec".
