The paper presents influence of external factors on results of bushing dissipation factor tanδ and capacity measurements performed on not energized transformer as well as with operation voltage using on-line method. There are discussed methods and real cases of measurements, with emphasized differences in results interpretation. Conclusions and literature are summarized.
