PROBLEM TO BE SOLVED: To provide a ground fault direction determination device, a ground fault direction determination system, a ground fault direction determination method, and a program capable of determining a ground fault direction in a power route only by measuring a current in the power route. A ground fault direction determination device 130 converts a waveform data acquisition unit 133a that acquires current waveform data in each phase of a three-phase electric circuit, and current waveform data before and after the occurrence of a ground fault acquired by the waveform data acquisition unit 133a. Based on the current vector generated by the current vector generation unit 133d and the current vector generation unit 133d that generates the current vector of each phase before and after the occurrence of the ground fault and the current vector of the zero-phase current after the occurrence of the ground fault. , And a ground fault direction determination unit 133e that determines the direction of the ground fault location on the electric path.
