Method and system for dynamic short circuit calculation

A computer program product embodied on a non-transitory computer readable medium, including instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• measuring at least one of instantaneous voltage and instantaneous current by each of a plurality of cable mounted sensors distributed on each phase carrying cable of an electric grid;
• 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.

A computational system for predicting short circuit events in an electric grid, the system comprising a processor and memory capable of:

• measuring at least one of instantaneous voltage and instantaneous current by each of a plurality of cable mounted sensors distributed over electric cables of an electric grid;
• 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.
