A novel full compensation method for the ground fault current of resonant grounded systems
Electrical Engineering, 2021The traditional arc suppression coil cannot compensate for the active and harmonic component of the ground fault current nor fully suppress the intermittent arc. For improvement, a novel full compensation method for the ground fault current of resonant grounded systems is proposed.
