摘要： Apparatus and method of water absorption for generator stator winding insulator using a cross capacitance are disclosed. The apparatus includes a sensor using a cross capacitance, and a water absorption testing unit for carrying out the water absorption test of the insulator of the stator winding of the power generator using the sensor. The apparatus determines whether the insulator absorbs water, according to thickness, using the cross capacitance, such that inferior winding is detected, a power plant is prevented from being suddenly stopped, costs for the maintenance are reduced, and the lifespan of the power generator is extended.
