1. A line sensor with power line fault analytics, comprising:
a wireless interface;
an e-field sensor;
a current sensor;
a processor communicatively coupled with the wireless interface, the e-field sensor, and the current sensor; and
memory communicatively coupled with the processor and storing:
at least one fault signature having an e-field template defining e-field attributes that occur in response to a line break, and a current template defining current attributes that occur in response to the line break; and
machine-readable instructions that, when executed by the processor, cause the processor to:
determine e-field key parameters based at least in part on e-field data, representing electrical field produced by a power line to which the line sensor is installed, received from the e-field sensor;
determine current key parameters based at least in part on current data, representing current through the power line, received from the current sensor;
normalize the e-field key parameters to generate normalized e-field key parameters;
cross-correlate the normalized e-field key parameters to the e-field template to determine an e-field match similarity;
normalize the current key parameters to generate normalized current key parameters;
cross-correlate the normalized current key parameters to the current template to determine a current match similarity;
determine a line break in response to both (a) the e-field match similarity being greater than an e-field threshold, and (b) the current match similarity being greater than a current threshold;
and
send, via the wireless interface, an alert to a computing device indicating the line break.
