Abstract

Abstract

A novel power frequency electric field measurement system based on high-performance MEMS electric field sensing chips is developed. Based on cross-correlation detection principle, a power frequency electric field demodulation algorithm of MEMS sensing chips that can inhibit background interference noise is proposed. And a small-scale, high-resolution electric field measuring probe is designed. Moreover, the system overall structure scheme is designed for implementation of high-accuracy demodulation electric field signals. The test result under power lines shows that the plotted curves of the developed MEMS system are consistent with Narda EFA-300.
