SELF-POWERED POWERLINE SENSOR

摘要

A self-powered powerline sensor (10) includes a core layer (18) for wrapping about an a.c. powerline (12); a winding layer, including a plurality of windings (20) to be energized by the a.c. powerline (12), disposed about the core layer (18); means (50-60) for sensing a condition in or about the a.c. powerline (12); and means (44) for sensing, for transmitting a signal representative of the sensed condition over the a.c. powerline.
