Abstract: A method is provided of ascertaining an unknown line (conductor) voltage at point X on a power line within an electrical grid comprises collecting raw voltage at or about Point X1 using a sensor; gathering additional data from data collection sources upstream (comprising, for example a substation) and/or downstream (comprising, for example, one or more smart meters) to Point X1 (constraining data); using raw voltage, and environment and line data (comprising at least one of GPS location of sensor, GIS data of the electrical grid, phase, type of conductor, total load on conductor), to calculate voltage range at Point X1; and using constraining data sequentially to bind (narrow and tighten) the voltage range from a determined range of possibilities to a likely absolute voltage measurement.
