Abstract:
1. An electric power supply apparatus attached to an overhead line to supply an electric power to a load, comprising: an electrode extending along said overhead line in a longitudinal direction thereof, with a dielectric being intervened therebetween; a capacitor defined by said overhead Line said dielectric and said electrode; an operation capacitance existing between said electrode and the ground so as to be in series to said capacitor; an inductor that is connected at one end to said electrode and at the other end to said overhead line so as to be in parallel to said capacitor; and an output section drawn from both ends of a parallel circuit including said capacitor and said inductor, wherein said parallel circuit is formed as a parallel resonance circuit, so that an electric power is output from said output section.
