There is an FCS paper that pre-dates that by about a decade. The guys at
Quebec Hydro set up GPS to monitor the phase state in their main distribution
network and wrote the paper. I don’t have an FCS DVD handy to dig it up. I
also have no idea if there is a copy outside a pay wall. They went into a bit
more detail on what they saw. It gives you a bit better feel for how it works
in the real world.
