Abstract
A system and method for the wireless synchronization of a self-powered power sensor (SPPS) to a central controller for calculating a value of an electrical parameter. The method includes receiving from a central controller a message that includes timing information of the central controller time base; sampling at least an electrical signal respective of a powerline connected to an SPPS; estimating from the samples of the at least an electrical signal at least a first electrical parameter, where the at least a first electrical parameter is adjusted using the timing information; generating a packet; appending to the packet the estimated at least a first electrical parameter; and transmitting the packet to the central controller.
