1. A computer-implemented method for predicting short circuit events in an electric grid, the method comprising:
distributing a plurality of cable mounted sensors on each phase carrying cable of the electric grid;
measuring at least one of instantaneous voltage and instantaneous current by each of the plurality of cable mounted sensors;
determining electricity generation sources feeding the electric grid;
determining voltage output for each electricity generation source feeding the electric grid;
determining cable length from each electricity generation source where short-circuit current may be higher than permitted short circuit current; and
calculating probability of an excessive short circuit event.
