PSM1700 PsimetriQ user manual
16-5
16.3 AC resistance and Q factor
AC resistance is measured the same way as inductance
with CH1 monitoring the voltage across the winding, and
CH2 monitoring the current through it via the external
shunt (source resistance).
The Q factor measurement is an effective way of detecting
a shorted turn either on a transformer, or on a choke
when using the transformer analyser fixture TAF02. When
using suitable conditions (often very different from the
normal operating conditions of the device under test) the
Q factor changes dramatically when a shorted turn is
present.
16.4 DC resistance
DC resistance is measured with the same circuit
arrangement as inductance and ac resistance, but dc
signals are used (refer to the chapter on the rms voltmeter
for the formulae for dc analysis).
