GIS Monitoring
Product model: EC3000GIS(OnlinePDM)
Product Brief:EC3000GIS is a set of online monitoring system for continuous monitoring and analysis of partial discharge signals in GIS. The system is mainly composed of UHF UHF sensor, DAU local monitoring host, terminal monitoring device and PD online advanced analysis software. The local monitoring host in the monitoring system is used to process and digitize the signals obtained from the sensors, and the upper computer is used to screen and analyze the PD signals, and to complete the PD recording and monitoring the development of the PD volume. The EC3000 Bureau's line monitoring device has been widely used in the State Grid's UHV 1000KV project, including Zhejiang Key 1000KV, Taizhou 1000KV, Beijing East 1000KV, Beijing West 1000KV, Tianjin South 1000KV and other national key projects.

  • EC3000GIS是一套用于连续监测和分析GIS中局部放电信号的在线监测系统,系统主要由超高频UHF传感器、DAU本地监测主机、终端监控装置和局放高级在线分析软件组成。监控系统中本地监测主机用于处理从传感器获取的信号并将其数字化,而采用上位机进行局放信号的筛选、分析并完成局放脉冲数值记录、监测局放量发展状况等功能。
