10.23 Application: Power Line Power Scavenging for Sensing. As part of a smart grid, one proposes to place sensors on
power lines to sense a variety of parameters such as temperature, current, corrosion, vibrations, and others and
transmit these parameters wirelessly to a central location. To do so, the sensors are placed on the power line itself by
attaching them to one conductor of the power line. To power the sensors and the wireless transmitter, one can use the
magnetic field produced by the line by designing an appropriate transformer. A solution is to place a toroidal coil
