发明名称 THREE PHASE POWER QUALITY MEASUREMENT USING ASYNCHRONOUS, ISOLATED SINGLE PHASE CIRCUITS
摘要 <p>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.</p>
