VOLTECH AT3600 USER MANUAL TRANSFORMER TESTS
TESTS AND TEST CONDITIONS VPN 98 - 024 PAGE 7.1.59.
In practice, the magnetising current waveform may have a transient component
following the switch-on of the test voltage. To give you repeatable accurate results,
the measurement does not start until any transient has settled.
The test signal can have a frequency in the range 20Hz to 5KHz, and an amplitude
from 5V to 600V depending on the type of external source used. The current rating of
a single AC Source Interface is 10A rms. See also the MAGI test which uses the
AT3600s internal generator which can provide up to 270V ac at 40W.
