【摘要】 定性分析了可能影响集中式绝缘在线监测系统监测结果的多种因素,包括传感器的角误差、信号的传输方式、PT角差、环境温湿度、并列设备的相间干扰以及A/D转换时的采样位数与采样速率。针对不同的影响因素提出了相应技术措施和对系统误差的处理方法。更多还原

【Abstract】 Qualitative analysis on many factors that may effect measurements results of on-line monitoring of HV apparatus insulation have been studied in this paper, which include angle error of sensor, transmission form of signals, angle error of PT, temperature and humidity of environment, interphase interference of the apparatus standing side by side and sampling bits and rate during A/D conversion. The solving methods for each different effecting factor and the processing method for the system’s error are offered.更多还原
