A device for monitoring an electrical insulation in the case of a vehicle electrical system of a vehicle, includes: a voltage source for generating direct voltages having a first and a second voltage value; a voltage-measuring unit between a positive and a negative power supply line of the vehicle electrical system for measuring a voltage between the positive and the negative power supply line; a current path between a positive current connection of the voltage source and the positive power supply line; a current-measuring unit in the current path for measuring a current flowing through the current path; a determining unit designed to determine an insulation resistance between the vehicle electrical system and an electrical ground from voltage measurement values of the voltage-measuring unit, current measurement values of the current-measuring unit, and the first and the second voltage value.
