摘要： The present invention impresses the data on the power signal by utilizing a saturable core reactor. The saturable core reactor uses two cores. Each core has both load windings and control windings. The control windings are selectively energized to alter an electrical characteristic of the current passing through the load windings. The saturable core reactor is designed with cores made of a highly magnetically permeable material so that the cores are easily saturated. The cyclical saturation of the cores achieved by the load current, and the selective saturation of the cores achieved by selectively applying a control current, results in "deformations" being selectively formed at the zero crossings of the load current waveform. These "deformations" can be selectively formed on the power signal to represent a binary data stream. Once the series of "deformations" is impressed onto the power signal, the "deformations" are communicated from one point on the power cable to another point on the power cable together with the power signal. The "deformations" are then read and transformed into a binary data stream. Thus, the power cable is converted from a mere power cable to a power cable capable of transmitting both power and data simultaneously.

摘要翻译： 本发明通过利用可饱和核反应堆给出功率信号的数据。 可饱和核心反应堆使用两个核心。 每个内核都有负载绕组和控制绕组。 控制绕组被选择性地通电以改变通过负载绕组的电流的电特性。 可饱和核心反应器设计有由高导磁性材料制成的芯，使得芯容易饱和。 通过负载电流实现的磁芯的周期饱和以及通过选择性地施加控制电流实现的磁芯的选择性饱和导致在负载电流波形的过零点选择性地形成“变形”。 这些“变形”可以选择性地形成在功率信号上以表示二进制数据流。 一旦将一系列“变形”印在电源信号上，“变形”就将与电源信号一起从电源线上的一个点传送到电源线上的另一个点。 然后，“变形”被读取并转换为二进制数据流。 因此，电力电缆从纯电力电缆转换成能够同时传输电力和数据两者的电力电缆。
