Abstract
A toroidal shaped transponder unit is connected to a live power transmission line by means of a tripping mechanism and a hinge assembly. The unit includes means for sensing the temperature and current of the power transmission line and for transmitting the information to a local receiver. The toroid housing includes an open frame mounting hub and spoke assembly for mounting the sensors without interfering with the thermodynamics of the transmission line. The unit further includes a power coil and core assembly for receiving magnetic emanations from the transmission line and generating power to operate the electronic components within the unit.
