Condition monitoring of high voltage power lines through self-powered sensor systems has become a priority for utilities with the aim detecting potential problems, enhancing reliability transmission and distribution networks mitigating adverse impact faults. Energy harvesting from magnetic field generated by alternating current flowing can supply required to operate without relying on hard-wiring or battery-based approaches. However, developing an energy harvester, which scavenges such limited source energy, requires detailed design considerations, may not result in technically economically optimal solution. This paper presents innovative simulation-based strategy characterize inductive electromagnetic harvester conditioning system. Performance requirements terms harvested output range, level core saturation be imposed. Different configurations, satisfy requirements, have been produced simulation models. The accuracy efficiency this approach is verified experimental setup based consists Si-steel unit. For worst-case scenario primary 5 A, maximum extracted as close 165 mW, resulting density 2.79 mW/cm3.
