Abstract
There is provided a grounding detection device and method. The grounding detection device may include an insulation tester and a grounding resistance providing unit. The insulation tester may be mounted in a first cabinet, electrically connected to a positive busbar and a negative busbar to detect an equivalent busbar-to-ground resistance, and grounded via the first cabinet. The grounding resistance providing unit may be mounted at least in part in a second cabinet different from the first cabinet, electrically connected to at least one of the positive busbar and the negative busbar to provide a grounding resistance, and grounded via the second cabinet. The insulation tester may determine, based on resistance values of the equivalent busbar-to-ground resistance and the grounding resistance, whether there is a ground fault or not for the insulation tester, the first cabinet, and the second cabinet.
