Design of a wireless vibration metre for conductor vibration monitoring

Abstract: Summary We present a vibration metre for conductor vibration measurement that is highly accurate due to its robustness against interference from the electromagnetic environment. According to the range of load currents in the transmission line, a power supply module based on induction charging is designed for the vibration metre. The module is composed of three parts: the mutual inductor obtains electrical energy from the transmission line based on the electromagnetic induction principle, the power controller m… Show more

“…The dynamic bending strain is calculated by measuring the bending amplitude of the point on the conductor located 89 mm from the last point of contact between the conductor and clamp, allowing the wire fatigue life to be predicted . In addition, a variety of wire vibration‐monitoring technologies have been implemented . However, the life prediction accuracy still cannot meet engineering requirements.…”
