The Impedance Phase Angle test can measure the impedance of a selected
winding using specified voltage (or current) and frequency conditions, and then
reports the equivalent impedance phase. An AC voltage is applied across the
winding under test and the complex impedance is determined from
measurements of the voltage across the winding and the current flowing through
it. The ANGL result is the phase of this complex impedance, it is the phase angle
between the voltage and current.
This test is normally used for audio & telecommunication transformers along with
the Z (impedance) test to check the complex impedance presented to the
transformers input and output. On selecting "ANGL Impedance Phase Angle"
from the 'available tests' window, the following dialogue box will be displayed:
