摘要
高压电网过电压在线监测数据采集方法利用新型的套管末屏电压传感器捕捉系统一次电压，可实时监测电网内部过电压和大气过电压，精确、完整记录过电压的变化过程，监测数据可为电力系统的事故分析及采取相应的防范措施提供科学依据，该监测系统运用了变频采样技术。
Using new - style voltage sensor mounted at the tap of transformer busing, data acquisition of on - line overvoltage monitoring of high voltage power network captures system primary voltage, it can real - time monitor overvoltage and atmospheric overvoltage of internal power network, moreover, record accu- rately change process of overvohage, monitoring power system and relevant preventive measures, skill. data can provide scientific basis for accident analysis of the monitoring system uses frequency- change sampling Key words：
