Abstract:

The main technical parameters of stator of the ALSTOMmade unit installed in the Three Gorges Left Bank Hydropower Station were introduced. The

test items and test standards of the stator whole withstanding voltage test and the cooling water system test were put forward; the test sequence and the

concrete implementation plans of different tests were drawn up; and some security matters were pointed out.

Key words: stator winding, electrical test, cooling water system, testing program, security matters
