Measuring audio transformer impedance
WebFrom this measurement, suitable resistance and capacitance standards are selected that will, when connected in parallel, result in an equivalent impedance magnitude. Since capacitors and inductors exhibit current flow with opposite phase, a current transformer interface is used to introduce a 180° phase shift in the capacitive current. WebFeb 2, 2024 · Actually, if the output transformer is measured properly, you want to measure the complete impedance of the primary. First, Load the 8 Ohm secondary with an 8 Ohm resistor. Now, measure the "5k" primary impedance at 1kHz. You will be measuring the complex impedance of the primary turns in series with the primary DCR.
