More Information
Summary:A system and method for the synchronization of a central controller wirelessly connected to at least one self-powered power sensor (SPPS). The method includes: sampling an electrical signal by at least one SPPS; estimating by the at least one SPPS a time of a sample of the electrical signal; generating a packet comprising packet components including a preamble, a synchronization field, and message data; generating synchronization information for the synchronization field of the packet; transmitting wirelessly the packet components; determining a time offset value for the packet, the time offset calculated from the time of the sample of the electrical signal and a transmission time-stamp of the synchronization information; and transmitting the time offset value by appending it to the packet, wherein the time offset value is used for the purpose of calculating at least an electrical parameter.
