The invention relates to a power distribution device with a ground fault protection function and a power distribution method. The power distribution apparatus may include one or more power distribution controllers and a processor coupled to each power distribution controller. Each power distribution controller can comprise one or more groups of power control units and one or more corresponding cross-core current transformers. And each group of power control units comprises three power control units. Each cross-core current transformer can be used for sensing cross-core current of three-phase output current of the three power control units corresponding to the cross-core current transformer. The processor may be configured to receive a sensed cross-core current from a cross-core current transformer; and transmitting a turn-off signal to each of the three power control units if the sensed cross-core current is not equal to zero. According to the power distribution device disclosed by the invention, the grounding fault protection function can be realized without changing the architecture of the existing power distribution device, and the safety of a power supply network is improved.
