Development of Online Monitoring Reference Devices for Transmission Line Aeolian Vibration

In order to improve the accuracy and the reliability of the measurement data of transmission line aeolian vibration online monitoring devices, a reference device is designed in this paper. Firstly, a vibration source is developed to generate the standard vibration(frequency output range: 0 ~200 Hz,amplitude output range: 0 ~1.5 mm). Secondly, a test interface is designed so that the output of the vibration source can be effectively measured by the transmission line aeolian vibration online monitoring device. The reference device has been tested with the higher level vibration reference calibrator. The test result indicates that the reference device reaches to the design requirements and can calibrate the whole of the transmission line aeolian vibration online monitoring device.
