Abstract
A test device is provided. The test device includes test components, power supplies, an alternating current (AC) power detection circuit and an alert module. The power supplies convert an AC power through a first wire, a second wire and an earth wire to a direct current (DC) power and supply the DC power to the test components. The AC power detection circuit receives the AC power through the first wire, the second wire and the earth wire to determine whether both of voltage differences between the first wire and the earth wire and between the second wire and the earth wire is outside of respective predetermined ranges. When both of the voltage differences are outside of the corresponding predetermined range, the AC power detection circuit controls the alert module to generate an alerting signal.
