Beschreibung
Zusammenfassung:	An electromagnetic-induction supply device may comprise: a current transformer installed on a power line and including one or more coils, a first core, and a second core; and a breaker unit connected to at least one of the one or more coils, wherein the breaker unit forms a closed circuit with the at least one of the one or more coils to switch the current transformer to a short-circuit mode in which the first core and the second core can be separated. Therefore, when the electromagnetic-induction power supply device is brought close to or installed on a live power line, the breaker unit prevents the formation of a magnetic field and thus the electromagnetic-induction power supply device can be easily attached/detached to/from the power line.
