Abstract
The paper deals with a data acquisition and processing method for evaluating the unilateral magnetic pull and a procedure for magnetic centring of synchronous hydro generators rotors using a dedicated system for electrical machines, developed on the LabVIEW National Instruments environment. Finally, the experimental results are presented before and after the application of the procedure for reducing the unilateral pulls obtained for a synchronous hydro generator of 9330 kVA and 215 rpm. The presented method can be useful in the frame of refurbishment procedures of synchronous hydro generators.
