Voltage Transformer
5 - 15
Measurements
Once all settings are defined, press the I/O (test start/stop) push-button to start
the test.
The test voltage increases in a ramp characteristic from 0V to Vtest. Then Vtest
is kept and injected for the time period set in the "Time" data entry field and the
measurements are taken. Next, the ramp decreases again.
When the measurements are taken, finish the test by assessing it.
To learn more about test assessment, refer to ”Test Assessment” on page 10-2.
VAC: injected voltage from 2kV AC output at the time the test turned
off
IAC: measured current between the transformer’s primary and
secondary windings at the time the test turned off
Imax: maximum measured current between primary and secondary
winding during the entire test cycle
