Method and system for dynamic short circuit calculation

A method, and a system and/or computer program implementing the method, for predicting short circuit events in an electric grid, the method including: distributing a plurality of cable mounted sensors on each phase carrying cable of the electric grid, measuring one or more 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, and determining cable length from each electricity generation source where short-circuit current may be higher than permitted short circuit current.
