A device (110) for monitoring a capacitor (105) for supplying electrical power comprises a direct voltage source (125) for charging a capacitor (105) that can be connected to the device (110) to a predetermined voltage, an alternating voltage source (130, 135) for supplying the capacitor (105) with a predetermined alternating voltage, a determining device (140) for determining a residual ripple of the alternating voltage and an output device (170) for outputting an error signal if the residual ripple exceeds a predetermined threshold value.
