ABSTRACT:
A ground detector includes a pair of lines, a first series circuit, a reference portion, a second series circuit, and a detection point. The first series circuit connects the lines to each other. The first series circuit includes first capacitors that are connected in series. The reference portion is connected to a portion of the first series circuit between two of the first capacitors for DC insulating the lines from the reference portion. The second series circuit connects the lines to each other. The second series circuit includes second capacitors that are connected in series. The detecting point is provided in the second series circuit. Each of the lines is connected to the detecting point through at least corresponding one of the second capacitors. The ground detector detects a change of impedance between the lines and the reference portion based on a change of potential of the detecting point with respect to potential of the reference portion.
