Customer’s demand
|
|
|
Our customer needs a high current output transformer in series connection for the thermal calibration of motor circuit breakers and automatic fuses. There should be the possibility to set three current ranges to adjust the needed constant current of the fuse.
|
|
|
Solution
|
|
|
We construct a one-phase transformer. The divided high current winding will be connected in parallel. For an optimal junction to get a very small Uk we also divided the primary winding.
