VT Winding Resistance Measurement Using QuickTest

To measure the winding resistance of VTs using the CT Analyzer, you can either
use the Quick Test function of the CT Analyzer (see chapter 8 on page 135) or
the CTA QuickTest PC tool which is part of the CT Analyzer PC Toolset.
Observe the general safety rules in section 2.1 on page 21.
For VT winding resistance measurements using Quick Test, connect the
CT Analyzer as shown in Figure 2-17. For a detailed description on how to
perform such measurements, please refer to section 8.8 on page 154.
Connect the "Output" sockets and input "Sec" of the CT Analyzer to the winding
to be measured.
