16 Transformer analyser
The transformer analyser mode allows a comprehensive
set of measurements to be performed on a transformer at
a single frequency or automatically swept over a range of
frequencies.
The tests available are:
turns ratio
inductance
leakage inductance
ac resistance and Q factor
dc resistance
interwinding capacitance
magnetising current
insertion loss
return loss
single harmonic distortion
total harmonic distortion
longitudinal balance
The transformer analyser function is invoked, and the test
selected, by the MODE key.
The easiest way to connect to the transformer in the
various configurations for the different test is to use the
transformer analyser fixture (see accessories) that
connects to the PsimetriQ BNC connectors and also to the
PsimetriQ extension port. Using the fixture, with
appropriate source and load resistors, the test
configuration and winding selection is selectable from the
front panel. Active buffers within the fixture minimise the
effects of stray capacitance and inductance.
Measurements can be made without the automatic fixture
by manually making the appropriate connections to the
transformer and resistors (set the fixture option in the AUX
menu to ‘none’).
