Turns ratio (N) Approximate the turns ratio (N) by connecting a resistor in the secondary as shown in
Figure 5-19 (a). From the impedance value measured at the primary, the approximate turns ratio
can then be calculated. Direct turns ratio measurement can be made with a network analyzer or
built-in transformer measurement function (option) of the 4263B LCR meter. Obtain the turns ratio
from the voltage ratio measurements for the primary and the secondary, as shown in Figure 5-19
(b).
