Abstract: This paper investigated and surveyed the installation rate, the usage rate and the electrified rate etc current situation of residual current protective device in rural area of Xinjiang and discovered that under humid environment and power equipment suddenly operation, there existed the phenomenon of misoperation and non-operation. The operation cause of residual current protective device was analyzed to realize the corresponding solution of rational distribution and structural improvement.
Key words: residual current protective device; reliability; misoperation; non-operation
