Experiment and research of voltage sensor of high-voltage transmission line based on inverse problem of electric field
摘要
Abstract
This paper proposes a new approach of voltage measurement in high voltage (HV) grid. A new electronic voltage sensor used for HV transmission and transformation equipment is manufactured based on charge induction calculated by inverse problem of electric field. Inverse problem of power frequency electric field is deduced, while voltage calculated flow is reported and primary sensor model is designed. The error influenced by electric field distortion is analyzed and validated by the actual experiments. Experimental results show that the effective value of detected voltage is precise and the distortion of voltage shape is small. The proposed sensor is suitable for detecting voltage of HV transmission and transformation equipment and mildly influenced by electric field distortion.关键词
