METHOD OF ANALYZING QUALITY AND CONDITION OF TRANSFORMER OIL AND OIL-FILLED EQUIPMENT, AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: physics.;SUBSTANCE: invention relates to diagnostics of oil-filled electric power equipment and to method of transformer oil quality and condition analysis. When the method is implemented, optical radiation is passed through the cell and a continuous signal spectrum is recorded in the entire range λ = 400–800 nm. Evaluation of oil quality and condition includes calculation of oil contamination parameter K = I_pas(λ)-I_scat(λ), where I_pas(λ) is spectrum of optical radiation passed through analysed oil; I_scat(λ) is spectrum of radiation scattered by analysed oil.;EFFECT: technical result consists in expansion of range of diagnostic parameters and increase in accuracy and efficiency of diagnostics.;8 cl, 4 dwg
