具有同时性综合相对测量法的应用

介绍并讨论了综合相对测量法在绝缘介损在线监测中的原理、处理过程及其应用。该法在环境因素不变条件下能减少测量扰动,提高准确性和稳定性,得到较好的结果。通过对环境因素变化瞬时性的研究,提出测量同时性观点以解决综合相对测量法在实际测量中存在的误判问题。现场试验表明:采用具有同时性的综合相对测量法能够很好地消除干扰带来的测量误差,准确判断设备运行状态。

Application of Synthetical Relative Method Including Synchronously Measuring in On-line Monitoring of Dielectric Loss Factor for Insulation

This paper introduces applications of synthetical relative method in on-line monitoring of dielectric loss factor, and discusses its principle and use in detail. Under the constant environment condition, the synthetical relative method reduces measuring disturbance and increases accuracy as well as stability, gets better results. On the basis of the synthetical relative method, through researching the of variability of environment factors, this paper puts forward synchronously measuring idea in order to deal with miscarriage of justice in this method. The experimental results show that the proposed method powerfully reduces the measuring error caused by disturbances and accurately judges the status of equipment.
