    • A method of performing line insulation monitoring of a pair of conductor lines (L1, L2) at least partially located in a cable, comprising the steps of: a) providing a first power switch (101) in a first conductor line (L1) of the pair and a second power switch (102) in a second conductor line (L2) of the pair, b) providing a line insulation monitor (27) at a first end of the pair of conductor lines (L1, L2), electrically connected to the pair of conductor lines (L1, L2), c) at the second end of the pair of conductor lines (L1, L2), electrically connecting the first and second conductor lines (L1, L2), d) placing the first and second power switches (101, 102) into a monitoring configuration wherein the first power switch (101) is closed while the second power switch (102) is open, and e) using the line insulation monitor (27) to monitor the insulation of the conductor lines.
    • 一种对至少部分地位于电缆中的一对导线(L1,L2)进行线路绝缘监测的方​​法,包括以下步骤:a)在第一导线(L1)中提供第一电源开关(101) 所述对和所述一对的第二导线(L2)中的第二电源开关(102),b)在所述一对导线(L1,L2)的第一端处提供线路绝缘监视器(27),电连接 (L1,L2)的一对导体线(L1,L2),c)在一对导体线(L1,L2)的第二端,电连接第一和第二导线(L1,L2),d) 第二电源开关(101,102)变成监视配置,其中第二电源开关(101)在第二电源开关(102)打开时关闭,以及e)使用线路绝缘监视器(27)来监视第 导线。
