Abstract
A device (1) for assessing the corrosion of the transformer windings in an oil-insulated transformer comprising a copper conductor (2) immersed in the oil. The change of the resistance of the copper conductor (2) over time is measured, e.g. using a Wheatstone bridge (2, 12a, 12b, 12c), and used to assess the degradation of the copper exposed to the insulation oil. The temperature of the copper conductor can be controlled by an heating element and a temperature sensor.
