    On-line diagnostics of power transformers

  • Original language description

    A condition of oil-paper insulating system is principal diagnostic indicator for failure-free operation of power transformers. During the operation of the transformer ageing of the insulating system appears, which may cause changes of its important electrical and mechanical properties. Many factors work simultaneously on the insulation during the operation and the particular effects influence each other as well. The material ageing is also affected by changes of operating properties. Ageing rate of organic components, which compose the insulating system, is mainly accelerated by temperature, humidity and oxygen presence. The diagnostic system, which is mainly applied during the shutdown of the transformer, contributes to the detection of the ageing level and to the judgement of residual working life. Also on-line diagnostic systems are currently more applied, especially for strategically significant devices or in cases, when appeared failure could lead to considerable economic waste.
