$25-50 USD / hour

Design a circuit to collect (harvest or couple) AC power from the EMFs generated by overhead 3 phase AC electric transmission lines/circuits in order to power a remote, autonomous, 30 W field computer and sensor system. Such systems are located at the periphery of high-voltage transmission line ROWs (Rights Of Way). Minimum distance to the overhead phase conductors is ~ 20 meters. Power harvesting/coupling mechanism and design can be based on AC Magnetics (induction) or AC Electrostatics; I have significant experience in sensing and in obtaining power using AC Magnetic Induction, and would prefer an AC Electrostatic Approach. A DC Output is desired, but low-voltage (<220 Vac) could be used. High-voltage overhead transmission lines/circuits range from 69 - 765 kV and, typically, carry 100 - 1000 A. Initial work should target 500 kV with a 500 A load.

Hi!I am a student of electrical engineering at Simon Bolivar University, and here the program has a deep emphasis in electrical power systems, I took course of power electronics, transmission lines and electric machinery and I have worked in electrical design of controllers and current transformers for remote protection systems, i work with COMSOL, MATLAB and solidworks for my design and i have experience using this computational tools. We can talk more about your project by the chat for develop the mechanics that do you want for de computer and sensor systems. Of courses, I am familiar with the wireless induction power system too
