Systems for determining a phase of a device coupled to an electrical distribution system. The system includes a number of gateway devices configured to transmit a synchronization signal. The gateway device receives a node response message from a first node...

Provided are a data alignment method, a differential protector, and a differential protection system. The data alignment method comprises: obtaining first sampled current data from a first sampling device; receiving a second message from a second different...

Methods and systems for synchronizing an electric grid having unbalanced voltages are provided. Voltage vectors may be synchronized in a phase-locked-loop configured to maintain synchronous operation of the grid even when the voltages are unbalanced. For e...
