摘 要:為測量容性設備的介質損耗因數(tanδ),對比分析了過零比較法、諧波分析法與相對比較法,并在此基礎上提出了改進的相對比較法,該方法引入只含有基波的中間參考量,通過中間量計算相位差,將諧波分量放大并引入直流分量進行模擬實驗。實驗結果表明,該方法消除了諧波大小對測量結果的影響,測量精度高,抗干擾能力強。
關鍵詞:容性設備;介質損耗因數;過零比較法;諧波分析法;相對比較法;改進的相關比較法

Abstract: In order to measure the dielectric loss factor of capacitive equipment (tanδ), this paper analyzed the over-zero comparison method, harmonic analysis method and relative comparison method respectively, and on the basis of this, this paper put forward the modified relative comparison method, which introduced the intermediate reference quantity with fundamental wave, calculating the phase difference via intermediate quantity. The harmonic component was amplified and the DC component was introduced to simulate the test. The result shows that this method eliminates the influence of harmonic quantity on the measurement results with measurement of high precision and strong anti-interference ability.
Key words: capacitive equipment; dielectric loss factor; over-zero comparison method; harmonic analysis method; relative comparison method; modified relative comparison method
