1. A method for unsupervised power-line event location within a power-line network, comprising:
receiving e-field measurements from a plurality of line-mounted sensors located on one or more power lines in the power-line network;
converting the e-field measurements to voltage approximations;
constructing a feeder model of the power-line network based at least in part on the voltage approximations by at least:
identifying nodal voltages as changes within voltage waveforms at individual ones of the plurality of line-mounted sensors between a first cycle prior to an event and a second cycle after the event;
identifying line currents as changes within current waveforms at the individual ones of the plurality of line-mounted sensors between the first cycle and the second cycle; and
using the nodal voltages and line currents, determining resistance and inductance of individual line segments of the power-line network, the individual line segments being between individual ones of the plurality of line-mounted sensors;
identifying the event within the power-line network; and
identifying a location of the event based at least in part on the feeder model.
