A VOLTAGE SENSING UNIT FOR SENSING VOLTAGE OF HIGH-POWER LINES USING A SINGLE-CONTACT POINT AND METHOD OF USE THEREOF

摘要

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 X using a sensor; gathering additional data from data collection sources upstream (comprising, for example a substation) and/or downstream (comprising, for example, smart meters)to Point X (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 X; and using constraining data sequentially to bind (narrow and tighten) the voltage range from a determined range of possibilites to a likely absolute voltage measurement.
