Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  present field test results of a low-cost fault detector for medium voltage por lines. Three devices are clamped on the lines and measure current with induction coils up to 190 A. The sensors harvest energy inductively from the line current. They are synchronized by radio and sum current of three phases is calculated.  compared the measured sum current with a substation reading during earth faults. With fault resistances beten 0 - 5000 Ω the full scale error of sum current was beten 0.2 - 4.0 %. In a normal state the maximum error was 2.6 %. Earth faults up to 330 Ω re detectable. The energy harvesting provided adequate operating por for the tests, but not yet for continuous operation.
