Description of the Related Art As a conventional live line insulation diagnostic device, for example, a technique disclosed in Japanese Utility Model Laid-Open No. 61-182857 is known. This conventional example will be described with reference to FIG. Each feeder in the power supply system has a current detector 6, 7, and 8. In the detector switching unit 2, the constant voltage generator 1 detects the current component superimposed in the power supply system. The current component selected by the detector switching unit 2 is calculated by the calculator 3 based on the superposition method, and is output to the display meter 4 as an insulation value from the calculation result.

がある。However, when the number of feeders and zones to be diagnosed reaches a large number, it is necessary to attach a large number of current detectors 6, 7 and 8 for each portion to be diagnosed, and the detector switching unit 2 is required to be attached. Since the switching mechanism also becomes large-scale, a problem occurs in terms of maintenance.
Conventionally, since the above-mentioned problems exist, the number of feeders to be diagnosed and the number of diagnostic zones have been limited, but there is a problem that it is not possible to cope with stricter system insulation monitoring in the future.
