• 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
  文中选择“比湿”综合校正法和两种传统校正法，分别对西高所为羊八井、拉萨、羊湖110kv变电所设备所做的人工气候室模拟试验数据及云南中试所做的zs - 110工频放电电压试验数据进行校正计算，将试验电压的校正值与试验设备的标称耐受电压水平进行比较分析；认为： “比湿”综合校正法的校正值与设备耐受电压水平基本相等或接近，而两传统校正法的校正值大多高于设备耐受电压水平；进一步证明， “比湿”综合校正法是目前诸多校正法中较为完善的，能真实地反映大气参数对电气设备外绝缘放电电压的影响程度的校正法，在高海拔电力工程设计中应推广应用。
