Abstract
The invention relates to electrical activity sensor attachable to a power cable of an electrical device for detecting an impulse generated in the power cable in response to a change in electrical power state of the electrical device. The electrical activity sensor includes an antenna assembly having an antenna element operable to magnetically couple with an electrical pulse generated in the power cable to induce an electrical signal in response to a change in electrical power state of the electrical device. The antenna element is shaped in a plurality of loops.
