Street Lamp Cable Anti-Theft, Terminal Controller

Function introduction
Voltage parameters real-time monitoring of distribution transformer and circuit, power failure time. Monitoring of power system voltage quality, harmonic voltage component to monitor power, the supply voltage, harmonic components of the whole point and time interval statistics;
Equipped with a special sensor and power transformer winding shell, the power transformer is damaged, move the tilt monitoring alarm;
Real time transmission parameters through the Chinese SMS;
At the same time control center in real-time transmission to ten groups of mobile phone number and system;
Users can set the remote automatic (can be set at regular intervals for 1 to 25 hours) timing transmission electrical parameters;
A plurality of DL-10V-GSM Chinese SMS voltage monitor through the GSM-8700 system control center can constitute a system of power network voltage quality monitoring and early warning of large;
Shell die-casting full sealed, waterproof, anti jamming performance is good, suitable for field installation. Overvoltage, overcurrent protection and lightning protection, loss of data protection, 72 hours without loss.
Monitoring data
The 1 voltage quality data including:
· Total running time time, qualified, qualified rate;
Ultra limit time, over the upper limit, lower over time, the rate of ultra limit rate;
· Maximum voltage value, the minimum voltage and time.
The 2 harmonic monitoring data:
· Total harmonic voltage distortion rate, content and fundamental voltage component, 2 to 31 harmonic voltage component and content;
· Total harmonic voltage distortion is qualified and qualified rate, distortionand maximum value of the appearing time.
3 time statistics:
For the quality of voltage and harmonic components can be statistics and assessment period;
* according to need to 24 hours for 1 to 8 hours.
