G Measuring with 2 WR-Meters at the same time
It is possible to measure the high and the low voltage side of a transformer at the same time
utilizing 2 Winding Resistance Meters. This makes sense if you want to have two different
measurement currents at the same time between the high and the low voltage side during a Heat
Run Test.
The following points must be considered for this measurement application:
NOTE:
Always use the 2 windings on the same core and connect them in the
same current direction. To find out the corresponding windings of a
transformer, you can use the table from chapter F Measuring high- and
low-voltage-side in series on page 125.
Start measurement!
Start the measurement on the high voltage side first. When the current is
flowing on the high voltage side, press “Start” on the instrument which is
connected on the low voltage side.
Stop measurement!
Upon obtaining the test results, First stop the current on the low voltage,
then stop the current on the high voltage side.
