Systems and methods for electrical connection monitoring using cable shielding are described. For example, a system may include a high-voltage power supply; a first high-voltage cable including a first conductor connected to the high-voltage power supply and a first shielding that encircles the first conductor; a second high-voltage cable including a second conductor connected to the high-voltage power supply and a second shielding that encircles the second conductor; and a continuity detection circuit connected to the first shielding and to the second shielding, wherein the second shielding is connected to the first shielding to form a loop with the continuity detection circuit.
