High pressure device based on electromagnetic induction
The new device is designed to obtain power from the induction electromagnetic(EM) energy around the high voltage power lines. The equipment transforms the induction EM energy into electricity to supply stable power for other ambient equipment. As a longterm and steady power supply, it is widely used for detection, inspection, supervision and thief prevention equipments near high voltage power lines.
