A conductor is a poor insulator because it has a low resistance to such flow.

导体可说是不良绝缘体，因为它的电阻很低。

Therefore, to determine the potential distribution of insulator string is very important to detect the poor insulator and safety and stable operation of transmission line.

因此，确定绝缘子串电位分布，对检测低、零值绝缘子，确保输电线路的安全、稳定运行具有重要的意义。
