摘要
以电压、电流过零相位差原理为基础。分析了测量的误差来源，给出了计算公式；利用单片计算机和配套的软件，作为信号采集、数据处理和计算的工具，实现了对高电压电容型设备介质损耗（tgδ）、等效电容（C）和系统频率（f）的在线测量。
Based on the principle of phase difference between voltage and current at their crossing zero points, are analysed the error souroes and the corresponding calculating formulae are providid. Using a single-chip microcomputer and related software as tools of signal collecting, data proessing and caculating,the parameters on-line measurment of the dielectric loss (tgδ),equivalent capacitance (C) of high-voltagr capacitive apparatus and the power system frequency (f) is achieved.
