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 manages the charging and discharging of a lithium battery, and the lithium battery supplies power to all modules and sensors. A cantilever beam displacement sensor is used to measure the vibration amplitude of the conductor. Moreover, a calibration method based on two‐dimensional regression is proposed to address the linear variation of the sensor output due to frequency variations. The corresponding test platform for power supply and accuracy is established, and the experiments verify the feasibility and accuracy of the vibration metre. Furthermore, the vibration metre is tested on a conductor spanning 105 m at Xi'an Polytechnic University. The test data show the number of amplitudes appearing at different frequencies within 10 days, which indicates the characteristics of vibration during this time.
