Abstract
Abstract A signal is received from a first portion of a power line and at least a portion of the signal is converted to a non-electrically conducting signal. The non-electrically conducting signal may be communicated to a non-electrically conductive communication path. In this manner, the non-electrically conducting signal may have properties that do not provide imminent danger from human contact.
