A direct current power supply assembly comprising a bus bar system (2) and a fault detection system (6) adapted to detect ground faults in the direct current power supply assembly. The bus bar system (2) has a positive bus bar (BB+) and a negative bus bar (BB-). The fault detection system (6) comprises a capacitor arrangement (62) comprising a first capacitor (C1) connected between the positive bus bar (BB+) and a middle point (PM), and a second capacitor (C2) connected between the negative bus bar (BB-) and the middle point (PM), a resistor arrangement (64) providing a high resistance between the middle point (PM) and a ground potential,and a detector arrangement (68) adapted to detect a fault situation if a voltage value of the middle point (PM) is equal to or greater than a first threshold voltage.
