<p>An apparatus includes a voltage sensor circuit coupled to first and second components of an electrically conductive assembly and configured to generate an output signal representative of a voltage between the first and second components. The apparatus further includes a radio frequency (RF) transmitter circuit configured to receive the output signal and to transmit a radio signal representative of the voltage. The first and second components may include, for example, respective first and second mechanically connected conductors, e.g., first and second conductors bolted together. In some embodiments, the first and second components may be coupled via more than one interconnection of conductors. In some components the first and second components may be components of a single conductor (e.g., a wire or bus bar) or a fuse. The RF transmitter circuit may be included in a radio frequency identification (RFID) tag integrated circuit.</p> |
