4.1 Error Message "Excitation current too high"

This message is displayed if the excitation current exceeds expected values. This value is set to 500 mA.
The excitation current can be reduced by selecting lower test voltages from the device menu.
Figure 4-1:
Error message
"Excitation current too high"
Possible reason for this is the transformer is drawing too much current. In that case, the test should be
repeated with a lower test voltage. Another reason may be the connections are reversed. If there are no
connections errors found, there may be a short circuit within the transformer itself.

4.2 Error Message "Turns ratio too low"

This message is displayed if the turns ratio of the transformer under the test is lower than 0,8. In this case
the user should check whether H and X cables are misplaced (reversed).
