  "textContent": "A ground fault detection apparatus includes a detection capacitor, termination resistors on positive- and negative-electrode sides, bypass resistors on positive- and negative-electrode sides, a bypass twin relay, twin relays on positive- and negative-electrode sides, and a control unit configured to compare a first full-charge voltage obtained with the positive-electrode-side twin relay in a first state, the negative-electrode-side twin relay in a second state and the bypass twin relay in a first state, with a second full-charge voltage obtained with the positive-electrode-side twin relay in a second state, the negative-electrode-side twin relay in a first state and the bypass twin relay in the first state, and determines that negative-electrode-side insulation resistance is lowered when the second full-charge voltage is smaller and when degree of the smallness is great.",
