SNV-300 Current Temperature And Fault On-line Monitoring Instrument

SNV-300 current temperature and fault on-line monitoring instrument   Current temperature on-line monitor and fault is the ring net switch cabinet, cable branch box, box installed in the power distribution network system becomes,for a real-time online monitoring device indicates the corresponding section of the cable short circuit and ground fault current, temperature and time. When the line is in trouble, the staff can quickly determine the fault section by the warning indication of the indicator, and find out the fault point. At the same time, real-time alarm information can be sent to the monitoring center server, a regional fault location and location  for monitoring the computer screen, the guide line patrol officers to quickly determine the fault section and find the point of failure. In order to solve the problem of fault finding, it provides the best way to improve the work efficiency, shorten the outage time, quickly restore the power supply, and improve the reliability and economic efficiency of power supply, which is of great significance.
