Abstract: A system and method utilize multiple, asynchronous, voltage isolated integrated power data circuits (IPDCs) to respectively determine one or more power parameters of a multi-phase power distribution system. In at least one embodiment, the power parameters represent differences between voltage phases of a multi-phase power distribution system. In at least one embodiment, the IPDCs each sense a voltage or current from a single phase of a three-phase power distribution system. Additionally, the IPDCs are electrically isolated from each other and, thus, in at least one embodiment, can utilize voltage divider or shunt resistor sensing without being subject to high voltages representative of the difference between voltage phases. Additionally, in at least one embodiment, each of the IPDCs utilizes a separate clock signal to determine phase sequence and phase angle deltas of one or more three phase voltages of the three-phase power distribution system.
Abstract translation: 一种系统和方法利用多个异步电压隔离集成电力数据电路（IPDC）来分别确定多相配电系统的一个或多个功率参数。 在至少一个实施例中，功率参数表示多相配电系统的电压相位之间的差异。 在至少一个实施例中，IPDC各自感测来自三相配电系统的单相的电压或电流。 此外，IPDC彼此电隔离，并且因此在至少一个实施例中可以利用分压器或分流电阻器感测，而不受代表电压相位之间的差异的高电压。 另外，在至少一个实施例中，每个IPDC利用单独的时钟信号来确定三相配电系统的一个或多个三相电压的相序和相位角增益。
