摘要
介绍了几种容性设备的在线监测方法,分析了它们的优缺点。在介损测量现场应用中,存在电网谐波、频率波动、相间干扰、电磁干扰等因素,同时非同步采样、非整周期采样会对测试结果产生影响。为了提高测量精确度,要在算法改进、硬件改进、测量方法上作进一步的研究。只有通过软件算法与硬件相互配合,才能提高测量的精确度。
Introduction was made to several online monitoring methods of capacitive equipment and analysis was made to their advantages and disadvantages. In field application of dielectric loss measurement, there existed harmonic influence, frequency fluctuating, inter-phase interference, electromagnetic interference and other interference factors, meanwhile asynchronous sampling and non-integer period sampling would influ- ence the test result, To improve the measurement accuracy, further research should be done on algorithm improvement, hardware improvement and measuring methods study. Only if the software algorithm corresponds to the hardware, the measurement precision will be improved.
