Ll - Leakage Inductance - Voltech AT5600 User Manual

C H A P T E R 1 4 - A T
14.6.8.
The Leakage Inductance for a particular transformer is tested by measuring the
inductance of a 'primary' winding when one or more 'secondary' windings have
short-circuited applied.
Select 'LL Leakage Inductance' from the available tests window, to display the
following form fill-in dialogue boxes as appropriate.
To program the test:
1. Enter the signal and frequency required for the test.
Note that the signal is normally entered as a current by selecting the 'uH' or
'mA' button; but you may optionally enter it as a voltage by selecting the 'mV'
button.
(Refer to Chapter 7 - 'Test Conditions', if you are unsure of the voltage and
frequency to use.)
2. Select (mouse click the button) the integration time you require.
'Medium' is the default setting. 'Long' will give more stable readings (for tighter
limits) at the expense of an increased test time, and 'Short' will test at the
maximum speed, but may give a slightly noisier reading. See 7.3 Explanation of
Integration.
3. Select the high and low terminals of the coil to be energized (primary terminals).
By clicking on the arrow to the right of the fill-in box, you will be provided with a
choice of possible terminals. Double-click on the name of the required terminal.
4. Select the secondary high and low terminals.
