In transformer, the concentration of the gases dissolved in transformer oil is associated with gas type, oil quality, oil temperature, transformer load, etc. which some are known, others are unknown. So it can consider that transformer is grey system and the theory of grey system is chosen as a mathematical framework to solve the problem of forecasting the change of gases.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Findings<\/jats:title><jats:p>If possible, the results should be accompanied by significance.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Research limitations\/implications<\/jats:title><jats:p>Accessibility and availability of data are the main limitations which model will be applied.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Practical implications<\/jats:title><jats:p>A very useful advice for power transformer fault diagnosis method based on dissolved gas analysis data.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Originality\/value<\/jats:title><jats:p>The paper presents a new approach of forecasting the value of gases in oil\u2010immersed power equipment and is aimed at unequal interval gases data which is used to GM.<\/jats:p><\/jats:sec>","DOI":"10.1108\/03684920910944209","type":"journal-article","created":{"date-parts":[[2009,5,30]],"date-time":"2009-05-30T07:05:58Z","timestamp":1243667158000},"page":"489-496","source":"Crossref","is-referenced-by-count":5,"title":["Short\u2010term forecast of the gas dissolved in power transformer using the hybrid grey model"],"prefix":"10.1108","volume":"38","author":[{"given":"Bin","family":"Song","sequence":"first","affiliation":[]},{"given":"Peng","family":"Zheng\u2010hong","sequence":"additional","affiliation":[]}],"member":"140","reference":[{"key":"key2022020219544851300_b1","unstructured":"Deng, J.\u2010L.
