Abstract: A system and method for measurement of one or more parameters of a power grid (10) is disclosed. This comprises determining a plurality of events in at least one power waveform on the power grid using at least two sensors (30, 50) and recording timings of the plurality of events in at least two different locations in the power grid. The data gathered is used to determine differences between the timings recorded in the at least two locations. A processing unit (40) is used to analyze the differences of the timings to determine the one or more parameters. These parameters include power flow, short circuits, and breaks in the power grid (10).
