Measurement of periodic voltage waveforms on secondary side of high voltage measuring device using Arduino

Abstract

Data acquisition on the secondary side is an important part of high voltage signal measurement. Based on Arduino microcontroller, a data acquisition (DAQ) system is developed. The frequency, root-mean-square value and DC component of periodic voltage waveforms can be measured by the system. The relative errors of the DAQ system are tested by comparing with standard voltage waveforms. The measurement range of the DAQ system is further discussed. The DAQ system in this paper is helpful to measure the periodic voltage waveforms on secondary side of high voltage measuring device.
