    • An electric leakage detection apparatus may quickly detect an electric leakage. An electric leakage detection apparatus includes a pulse generator that supplies a pulse to a coupling capacitor, a voltage detector that detects a voltage at the coupling capacitor, an electric leakage determination unit that compares the voltage detected by the voltage detector to a first threshold and determines presence or absence of the electric leakage of a DC power supply based on a comparison result. The electric leakage detection apparatus also includes a discharge determination unit that compares the voltage detected by the voltage detector to a second threshold lower than the first threshold and determines whether the detection voltage becomes lower than the second threshold by a discharge of the coupling capacitor. The pulse generator generates a new pulse when the discharge determination unit determines that the detection voltage becomes lower than the second threshold.
