Abstract：Through analyzing defects and its causes of existing small current grounding selector of high-voltage in coal mine, the paper introduced a new type of small current grounding line selection principle in high-voltage based on transient signal. And based on the principle, a mine-used small current grounding selector of high-voltage was developed with FPGA chip. The test result showed that the selector has high reliability and quick respond speed.
