Abstract
A vehicle energy transmission circuit is equipped with an insulation fault detection circuit that has a fault current measurement apparatus, a first high-voltage connector, a second high-voltage connector, a ground potential connector, a first measuring resistor, a second measuring resistor and a measuring switch. One of the high-voltage connectors is connected in series with a connecting point via one of the measuring resistors and the measuring switch. The measuring resistor connects the other high-voltage connector directly to the connecting point. The connecting point is connected to the ground potential connector via the fault current measurement apparatus. The fault current measurement apparatus is configured to record a current that flows between the connecting point and the ground potential connector. The fault current measurement apparatus is configured to record this current when the measuring switch is open and closed.
