DIAGNOSTIC METHOD AND APPARATUS FOR ASSESSING THE INSULATION CONDITION OF ELECTRICAL EQUIPMENT INSULATED WITH OIL |
摘要 |
A diagnostic method and apparatus for assessing the insulation condition of electrical equipment (3) insulated with oil (2). The method comprises the following steps: measuring the concentration of at least one gas dissolved in the insulating oil (2) of the electrical equipment (3); deriving at least one concentration parameter correlated with the gas concentration measured in a predetermined acquisition time interval; measuring electrical pulses relating to partial electrical discharges which occur in the electrical equipment (3) and which generate said pulses; deriving at least one discharge parameter correlated with the partial discharges measured substantially concurrently with the predetermined acquisition time interval; deriving a diagnostic indication about the insulation condition of the electrical equipment (3) as a function of the derived values of the concentration and discharge parameters. |
