ANUAL
Measuring the phase angle of the impedance will help to determine that the
part has been properly assembled using the correct cores and the right gauge
of wire.
Measurement Conditions
The AT Series Tester applies the specified AC voltage to the winding under
test. Using harmonic analysis, the phase angle of the impedance is determined
from the measured voltage and the current flowing through the winding.
ANGL is the angle of the complex impedance
φ
= tan
-1
(X / R)
Choosing Test Conditions
The voltage and frequency are usually determined by the final application of
the part under test.
