Resistance card

The Resistance card of the Advanced CT Test mode 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:
► 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 8.5.1 on page
113 for more information.
► Secondary winding resistance measurement (always required for CT testing for particular
calculations in the excitation and ratio test). See section 8.5.2 on page 113 for more information.
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.
