VT Ratio soft key.
Figure 8-11 CT-Quick card and Results card for VT ratio measurement
For the VT Ratio measurement type, the CT-Quick card holds the following
measurement quantities:
Warning: For VT ratio measurement, the CT Analyzer output has to be
connected to the primary side of the VT. Connecting the CT Analyzer output
to the secondary side of the VT by mistake will cause hazardous voltages on
the primary side!
Caution: VT ratio measurement using Quick Test is not a complete VT test!
This measurement only determines the voltage ratio of VTs. The CT Analyzer
does not perform automatic demagnetization after the measurement.
