Reason for Test
Checks power lost within
the transformer
Checks losses over a
range of frequencies
Checks power returned
by a transformer
Checks impedance at a
given frequency
Checks impedance at a
given frequency
Checks phase angle of
complex impedance
Checks phase of voltage
between windings
Checks imaginary part of
the complex impedance
at a given frequency
Adjusts transformer
parameter to desired
value during test
Performs external
switching as part of the
test program
Checks number of turns,
right grade of correctly
assembled core
material, where bias
current is greater than
LSB test can handle.
Checks number of turns,
right grade of correctly
assembled core
material, where bias
current is greater than
LPB test can handle.
Checks impedance at a
given frequency, while
applying a greater bias
current than is possible
with ZB test.
