Abstract
A system and method for the synchronization of a central controller wirelessly for determining values of electrical parameters. The method includes sampling an electrical signal via at least one self-powered power sensor (SPPS); estimating, via the at least one SPPS, a time-stamp based on the sampled electrical signal; estimating, via the at least one SPPS, at least a first electrical parameter; generating a preamble of a packet; generating a synchronization information for a synchronization field of the packet; transmitting the packet components wirelessly; determining a time offset value for the packet based on the time-stamp and the transmission time-stamp of the synchronization information; and transmitting the time offset value by appending the time offset value to the packet, wherein the time offset value is used for determining at least a second electrical parameter.
