Setting the Primary and Secondary Parameters Manually
To do this you will need to know the inductance of the primary and secondary
windings.
The optimum test conditions are chosen for an inductance value that is
between the primary and secondary (
L
m
).
Look up the recommended test signal for this inductance.
Enter the recommended frequency for this inductance as the test frequency.
The primary and secondary voltages can be calculated from the following:
If you calculate
V
s
or
V
p
to be greater than 5V, you should set 5V as your test
signal. If you calculate
V
s
or
V
p
to be less than 1mV, you should set 1mV as
your test signal.
