ABSTRACT:
A power supply generated through a set of current transformers is disclosed. The current transformers may be removably attached to a primary power line such as a high voltage power line. The power supply may be used to power a device or charge a battery for a device that requires a low voltage input. The power supply may be used in underground vaults and pad mounted chambers that contain high voltage power lines. The power supply may generate a low voltage direct current out put that is not available in the vicinity of high voltage power lines in an underground vault or pad mounted chamber.
