METHOD AND SYSTEM FOR ONLINE PASSIVE DETECTION OF PHASE CONNECTION OF POWER METERS

Some embodiments relate to a passive phase connection detection method for feeder power lines of an electricity distribution network. The method can include acquiring a list of meters for each feeder power line of the electricity distribution network; acquiring presumed phase connection data and historic voltage data of each meter of the list of meters of each feeder power line; assigning weight values to the presumed phase connection data to each meter of the list of meters of a first feeder power line; and initiating an analysis algorithm when new voltage data is detected for a first meter of the first feeder power line.
