  "textContent": "In first coupling capacitor, a first terminal is connected to a first connection point on a current path of power storage in a state of being insulated from a ground. Second coupling capacitor has a second terminal connected to a second connection point that is on a current path of power storage and is lower in potential than the first connection point, and second coupling capacitor has a first terminal connected to a second terminal of first coupling capacitor. AC output unit applies a predetermined AC voltage via impedance element to third connection point between the second terminal of first coupling capacitor and the first terminal of second coupling capacitor. Voltage measurement unit measures a voltage at third connection point. Determination unit determines the presence or absence of an electrical fault on the basis of the voltage measured by voltage measurement unit.",
