Correction of the Maximum Permissible Values of the Oil Acidity by the Minimum Risk Method

Autor: Oleg Shutenko, Serhii Ponomarenko

Publikováno v: 2021 IEEE 3rd Ukraine Conference on Electrical and Computer Engineering (UKRCON).

Based on the statistical analysis of the periodic test results of transformer oils condition for 231 transformers of 110 kV voltage the correction of the maximum permissible values of organic acid content in oil was carried out. It was found that the

Analysis of the Impact of Power Transformer Loading on the Transformer Oil Aging Intensity

Autor: Oleg Shutenko, Serhii Ponomarenko

Publikováno v: 2020 IEEE KhPI Week on Advanced Technology (KhPIWeek).

Operating temperature, which depends on the load of transformers, was analysed as a factor affecting the intensity of aging oils. The analysis results provided a quantitative assessment of the impact of transformer load on the drift intensity of oil
