Abstract
A method of water absorption for a generator stator winding insulator using a cross capacitance involves detecting a state of the insulator of the stator winding of the generator using a theory of the cross capacitance, and carrying out the water absorption test of the insulator of the stator winding of the power generator using the detected state in the detecting.
