Resumen:
This work presents the initial results of a newdesign of a complete non-contact voltage acquisition system,which allows the measurement of arbitrary waveform signals.The design is based on the results of a recent work, whereuncertainties and errors of the applied technique were analyzed,showing the impact of different design decisions on the finalaccuracy.The system is composed by a capacitive probe, an analog frontend,and a microcontroller-based digital signal processing stage.The results of different experimental test are reported, whereseveral signals are acquired with good accuracy. Even the instantaneouspower-line voltage signal is acquired without contact,with an error of 2%.
