<p>The device for measuring the ageing of a composite polymer insulator in a stator winding is characterised by two electrodes (2, 3) for constituting 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 may be carried out on site during the operation of the stator. <IMAGE></p> |
