An Active Ground Fault Location Method for Low-Voltage DC Lines Based on DFFT

An Active Ground Fault Location Method for Low-Voltage DC Lines Based on DFFT

For the problem of locating ground faults in low-voltage DC cable lines containing power electronic transformers, a single-ended volume fault location method using power electronic transformers with active injection is proposed for rapid fault detection and restoration of power supply. A sinusoidal...
