Abstract
Official abstract text for this publication.
An insulated state detection device includes a positive-side input terminal, a negative-side input terminal, a ground electrode, a ground fault resistance value calculation unit, a measuring state identification unit, a timing information generation unit that generates a timing information, automatically updates a value of the timing information by a predetermined value each time the ground fault resistance value calculation unit generates a new insulation resistance value, and reflects a state of the identification of the measuring state identification unit on the value of the timing information, and an information transmission unit that transmits the insulation resistance value calculated by the ground fault resistance value calculation unit and the timing information generated by the timing information generation unit to a host control device.
First claim
Opening claim text (preview).
What is claimed is: 1. An insulated state detection device comprising: a positive-side input terminal and a negative-side input terminal that are respectively connected to a positive-side power line and a negative-side power line of an output of a predetermined high-voltage DC power supply; a ground electrode; a ground fault resistance value calculation unit that calculates an insulation resistance value between the ground electrode and the positive-side power line and between…
