Faults diagnostics of high-voltage equipment based on the analysis of the dynamics of changing of the content of gases
Journal Title: Energetika - Year 2018, Vol 0, Issue 0
Abstract
In the article, the gas content of oils in high-voltage equipment with defects of different types is analysed. Typical gas contents and gas ratios for 38 most frequently encountered defects are presented and analysed. The dynamics of the gas content change in equipment during the development of defects was investigated. It is concluded that the development of defects in high-voltage equipment is accompanied by the growth of gas concentrations, which is known and widely used, and it helps stabilize the percentage of gases at strictly defined levels and detect defects at an early stage.
