Measurement and Analysis of Uncertainty of H 2 Concentration in Transformer Insulation Oil
ieee advanced information management communicates electronic and automation control conference(2019)
Abstract
According to the Evaluation and Expression of Uncertainty in Measurements, the author establishes the mathematical model for measuring the density of hydrogen in transformer oil by means of Gas Chromatography. Meanwhile the author analyses the resources of uncertainty and deduces formulas of uncertainty measurement. After calculating uncertainty of the components, the author obtains the synthesis uncertainty.
