A line selection method for single phase ground fault in coal mine power supply system based on wavelet packet

In view of problems of low accuracy and poor reliability of line selection methods for single phase ground fault in existing coal mine power supply system, a line selection method for single phase ground fault in coal mine power supply system based on wavelet packet was proposed. At first, transient...
