The Resistance card is only available if winding resistance measurement is
enabled in the Select Cards page (Default Test Card Selection or Select Cards
soft key in the CT-Object card).
The Select Cards page offers two different types of winding resistance
measurements for selection:
•
•
Depending on your selection on the Select Cards page, the Resistance card
shows the parameters and results for the primary winding resistance
measurement or the secondary winding resistance measurement only, or for
both measurements.

Primary winding resistance measurement (only required in case of a
perceptible primary winding resistance, i.e., if the primary winding actually
consists of multiple turns). See section 6.5.1 on page 106 for more
information.
Secondary winding resistance measurement (always required for CT
testing for particular calculations in the excitation and ratio test). See section
6.5.2 on page 106 for more information.
