PROBLEM TO BE SOLVED: To perform leakage detection without installing power supply wiring.SOLUTION: A leakage detection device comprises: a transformer which is detachably attached to a ground line and electromagnetically couples the ground line as a primary winding to a secondary winding; power supply means for obtaining DC power from an AC signal induced in the secondary winding on the basis of leakage current flowing in the ground line; detection signal generation means which operates on the basis of DC power and generates a leakage detection signal on the basis of the AC signal; and notification means which operates on the basis of the DC power and notifies the outside of occurrence of leakage on the basis of the leakage detection signal. |
