Abstract
A line sensor assembly is described for measuring line characteristics in a power line such as voltage, phase, current, etc. The line sensor assembly includes a set of electric field sensors, where the electric field sensors are positioned annularly about an axis of the assembly corresponding to an axis of a power line. A measurement circuit is configured to measure an electric field across each of the electric field sensors to produce a set of electric field measurements. The set of electric field measurements may be used to determine the line characteristics of a given power line.
