    Abstract According to the analysis on relevant standards，such as the national standard and IEC standard，the provisions of the current IEC standard are considered to be more applicable to problems like the setting value of the insulation resistance and testing voltage of insulation monitoring device installed in I T system.

    Key words　I T system Insulation monitoring device Setting value of insulation resistance

 

 

    摘 要 就I T系统内装用的绝缘监测电器的绝缘电阻的整定值、测试电压等问题，根据对国家标准、IEC标准等有关标准的分析，认为还是采用现行IEC标准的规定为好。

    关键词 I T系统 绝缘监测电器 绝缘电阻整定值
