The article adopts "humidity ratio" integrated emendation method and other two traditional emendation methods in emendation calculating on several group test results. The tests are : simulating test in artificial climate room on 110kV substation equipment of Yangbajing, Lasa and Yanghu by Xi"an High Voltage Lab; power frequency voltage discharge test of ZS-110 by Yunnan provincial electrical research academy. It compares and analyses the equipment test voltage emendated to standard atmosphere conditions with the equipment nominal withstanding voltage. And then it concluded that: the emendation value educed by "humidity ratio" integrated emendation method is basically equal or close to the equipment nominal withstanding voltage; but the values by two traditional emendation methods are mostly higher.It also proves that,"humidity ratio integrated emendation method is more perfect than any other methods, and it can reflect the influence degree of atmospheric parameters on electrical equipment outer insulation discharge voltage actually. The method should be spread in designing high elevation power projects.
