4.1.2 Comment
This is the minimum configuration for a Multiplexer use. A Raytech Winding Resistance
Meter is controlling a Multiplexer. Every winding resistance of one winding system (primary,
secondary, tertiary) can be measured with one cabling. In other words: to measure every
winding of a standard H/X transformer, you have to connect your system only twice to the
transformer under test.
In the example shown, the high voltage side is ready to be measured. Because of the delta
configuration of the primary windings, H1-H2, H2-H3 and H3-H1 will be measured. H0 cables
are not used.
After the cabling is done, for instance the user will give the command to switch H1-H2 and
start measurement. Both is done on the touch panel of the Winding Resistance Meter or by
remote. Then no change of cabling is necessary for next measurements. Just stop current
measurement, give the order to switch to H2-H3 or what ever and start measurement again.
NOTE
⇒
For Safety reasons, Multiplexer can not be switched while
measurement is running.
