　　目前我国工业与民用低压配电系统中，一般均采用接地和接零保护，也就是我们通常所说的TT和TN接地系统。 这两种系统对供电安全保护起到了一定的作用， 但由于TT和TN系统本身存在一定的缺陷和不足，在实际运行中仍有某些不安全因素，安装漏电保护器能弥补TT和TN系统的不足，是防止电击事故的有效措施之一，也是防止漏电引起电气火灾和电气设备损坏事故的技术措施， 可以进一步提高供电的安全可靠性。因此，漏电保护器在低压配电系统中被广泛地采用。

0. Foreword
At present China's industrial and civil low voltage distribution system, generally used to protect ground and then zero, that is what we usually TT and TN grounding system. Both systems supply security played a role, but TT and TN system itself has some flaws and shortcomings, in practice there are still some insecurity run, earth leakage protection devices can make up for TT and TN drawback of the system is to prevent electrical shock one of the effective measures is to prevent electrical fires and electrical leakage caused by the accident damage to equipment technology, we can further improve the safety and reliability of electricity supply. Therefore, the leakage protective device in low power distribution system has been widely adopted.
