 Correct IncorrectCapacitive coupling voltage induced into de-energized wires running parallel to live energized cables. Using a meter with Low-Z (low input impedance) bleeds off phantom readings.

What is 'Ghost Voltage' (phantom voltage) detected by high-impedance digital multimeters?

• Voltage from solar panel batteries
• A defective digital display LCD screen
• Induced capacitive coupling from adjacent live conductors; reduced or identified with a Low-Z multimeter
• Static electricity from nearby thunderstorms
