4.4. LS OR LP – WINDING INDUCTANCE (SERIES OR
PARALLEL CIRCUIT)
The inductance of a transformer winding may be tested using series or parallel
equivalent circuit models. An ac voltage is applied across the selected winding. The
voltage across and current through the winding are then measured using harmonic
analysis. The measured voltage is divided by the current to obtain a complex
impedance and the inductance is calculated.
On selecting ‘LS Inductance (series cct)’ or ‘LP Inductance (parallel cct)’ from the
Available Tests window, a dialogue box will be displayed.
or:
To program the test:
1. Enter the signal and frequency required for the test.
Note that the signal is normally entered as a voltage by selecting the 'mV' or 'V'
button; but you may optionally enter it as a current by selecting the 'mA' button.
