Short Circuit Impedance Settings - Raytech mini-ATOS Instruction Manual

10.6.1 Short Circuit Impedance Settings

The short circuit impedance main settings are as follows:
To select the test voltage. You can also add user defined test voltages to the list by tapping on
the + button
To select the test voltage frequency. The test frequency can be 50Hz or 60Hz. You should
select the test frequency according to the working frequency of the test object
Enter the Base Power or the maximum rated power of the transformer. With the Base Power
and the profile rated voltages, the impedance value will be shown also as precent value
Figure 78 shows the short circuit impedance temperature settings. In temperature settings, it is
possible to enable each of the 5 temperature channels to record. When there is an external
temperature probe, the External switch should be enabled. The reading value must be also entered
manually.
The mini-ATOS use the average of all temperature values for the temperature correction.
