Sažetak
A review of the two approaches of dissolved gas analysis – detailed fault diagnosis and trend analysis with fault indication – is given. The advantages and disadvantages of the two approaches under the aspects of measurement uncertainty, economic efficiency and integration into a condition assessment strategy are outlined. A concept of signal processing enhancing the capabilities of trend analysis and early fault indication is described. It is concluded that trend analysis with early fault indication is sufficient for most cases of an integrated condition monitoring system.
