Unusual amp reading on secondary of transformer

[naplespete57]

Just installed a delta delta transformer. When I ran the motor it is designed for I got the following readings.. Phase A 11.4 Phase B 14.1 Phase C 11.4.

Why the different reading? What should I check? Transformers only purpose is to run motor, nothing else is tapped out of it.

Is it a matter of concern?

Thanks!

What voltages did you have at the time of the reading?

 

[Pierre C Belarge]

Is the transformer and the motor installation new?
or
Is the motor existing and you are replacing the Xformer?

a)Check the No load primary voltage.

b)Check the secondary voltages when the Load in ON.

Currents are bound to follow the voltage difference.

AS noted above and.

Check primary unloaded/loaded.

Check secondary unloaded/loaded.

Check transformer taps.

Other factors orientation of amp clamp, check all connections, if possible measure resistance from secondary terminal to motor for voltage drop across conductors, do same for primary side from service to primary connections.

Possible motor winding issues (I have had motors in the past with this issue we (and others) did every test under the sun and found nothing.
