Failure in Wind Generator

Failure in Wind Generator

Failure in Wind Generator

(OP)
Dear All

Attached you will find  one picture of   failure, in one 2 Speed Low Voltage Squirrel Cage Induction  Wind Generator:  1300/250 KW 690/690 V 1219/248 Amps   1510(4 Y)/1008(2 D)  Rpm   50 Hz.
 

The Failure happened in the Low Speed winding,

What happened ?

Could be currents induced in the unergized winding circulating by transformer action? The problem could occur when the machine was working in low speed and one of the parallel path was opened in one phase?

Thanks for the Inputs
 

Regards

 

Carlos

 

RE: Failure in Wind Generator

Looks to me that the low speed winding had two parallel circuits and one of them got opened leaving the other to carry the full current.

RE: Failure in Wind Generator

During the generator works at a higher speed (4Y), the second winding (2D) must be open (both parallel circuits).
