ANGL: Angle of impedance
Ensures that the core material, wire resistance, number of turns and inter-winding capacitance combine to meet design specifications.
Unit of measurement, Degrees. Range -360° to +360° with a signal level from 1mV to 5V @ 20Hz to 3MHz
For transformers in applications that operate over a wide frequency range, e.g. audio transformers, the designer or the production department may have to measure the phase angle between the real impedance (resistive (R)) and imaginary impedance (inductive or capacitive (jXs)). The sum of R and jXs is commonly referred to as Z (total impedance). As the applied frequency is increased on an inductor the impedance increases and the impedance phase angle decreases up to the point of self-resonance, at this point the impedance phase angle is zero (also the highest impedance value).
