1. A power supply for receiving power input from a high voltage transmission line and providing a direct current power output to an electrical load operated at or near the potential of said transmission line remote from electrical ground, said power supply comprising:
- (a) a metallic structure supported in proximity to said transmission line remote from electrical ground;
(b) capacitor means electrically connected between said transmission line and said metallic structure for providing in response to the presence of high voltage on said transmission line an alternating current voltage, the magnitude of which alternating current voltage is dependent upon the capacitance of said capacitor means and upon stray capacitance between said metallic structure and electrical ground; and
,(c) power conditioning means electrically connected to said capacitor means for receiving said alternating current voltage and converting such voltage into a direct current voltage for the supply of direct current power to said electrical load.
