基于光纖的測(cè)量瞬態(tài)電場(chǎng)的球形傳感器

在電力系統(tǒng)中,除了電場(chǎng)的計(jì)算方法外,電場(chǎng)的測(cè)量也是一種很重要的手段。在一些特殊的場(chǎng)合,測(cè)量甚至是唯一的方法。介紹了一種可用來測(cè)量隨時(shí)間周期性變化或瞬變電場(chǎng)的球形傳感器,對(duì)球形探頭測(cè)量電場(chǎng)的基本原理和一、二、三維電場(chǎng)探頭的結(jié)構(gòu)及測(cè)量誤差做了分析,并介紹了二維球形傳感器測(cè)量系統(tǒng)及其應(yīng)用。
關(guān)鍵詞: 瞬態(tài)電場(chǎng); 探頭; 電場(chǎng)測(cè)量
Abstract : In power system ,beside field calculation ,the measurement of electric field is an important method. In some special case ,measurement is the only way. It is described that an electric field sensor for the measurement of time dependent periodic or transient electric fields. The basic theory of the measuring method and the geometry of the three kinds probes are described ,and the field measurement system with spherical sensor and its application are emphasized.
Key words : transient electric field ; probe ; electric field measurement
