System and method for measuring the aging an insulation of polymer mixtures for stator windings

摘要

The device for measuring the ageing of a composite insulator polymer in a coil of the stator, is characterized by two electrodes (2, 3) in order to constitute a capacitor with the composite insulator and a circuit (10, 11, 12, 13, 14) connected to the electrodes for measuring the loss angle of the capacitor. The measurement can be carried out on site during the operation of the stator.
