L2 – Inductance Match

 

Where Used 

The inductance match test calculates the ratio between two inductances on two 
windings. An equivalent series inductance measurement is performed on each 
winding by measuring the complex impedance. 

This test is suitable for switched mode power supply transformers, and audio & 
telecommunication transformers. It checks matching between windings. 

Measurement Conditions 

When calculating, inductance match the tester performs two inductance 
measurements. Firstly, the unit applies an AC voltage across the first winding; it 
then measures the voltage across and the current through the winding using 
harmonic analysis.  The measured voltage is divided by the current to obtain a 
complex impedance and the inductance is calculated. This is then repeated for 
the second winding. The inductance match is the ratio of first to second winding 
inductance. 

The test signal can have a frequency in the range 20Hz to 3MHz, and an 
amplitude from 1mV to 5V.   

Generally, it is not necessary to measure the inductance at the normal operating 
conditions of the transformer, which could involve, for example, voltage levels of 
hundreds of volts.  This is because the B-H curve can normally be assumed to be 
linear in the operating region, and the inductance measured at a low level 
represents the inductance that will appear in use.  

Also, it can usually be assumed that the inductance value does not vary 
significantly with frequency.  Therefore, although high frequencies are available 
with the tester, measurement frequencies above a few hundred kilohertz should 
be used with caution.  This is because the errors caused by the stray inductance 
and capacitance of your fixture may become much more significant at these 
frequencies. Compensation can be used to eliminate these errors. 

The following table suggests suitable test conditions for different values of 
expected average inductance:
