Service Condition:

Design Feature:

• Using intelligent controller control, complete function, reliable performance, automatic compensation method; can improve the power factor to more than 0.9;
• Real-time display of power grid power factor, display range: lag (0.00-0.99), advance (0.00-0.99);
• With overvoltage, overharmonic, overcompensation, system fault, phase deficiency, overload and other comprehensive protection functions;
• Memory of the set parameters, the system will not be lost after the power failure, after the power grid returns to normal, automatically enter the operation state, without personnel on duty;
• According to the load balance of the grid, compensation can be adopted by the phased compensation or mixed compensation;
• Strong anti-interference ability, can resist the amplitude of 2000V interference pulse directly input from the power grid, higher than the national professional standard.

Distributable Power Network Monitoring Function

• Real-time measurement and integer point to record the three-phase voltage, current, frequency, active power, reactive power, power factor, active power degree, active power degree, total voltage, current distortion rate and 2-25 harmonic content on the low-voltage side of the transformer;
• With RS-232 and RS-485 interfaces, you can set and read meter reading, equipment testing, time real-time measurement data and recording data through handheld computer data replication or wireless recording functions;
• Data analysis function: operating load data, statistical query: comprehensive analysis of power quality, voltage pass rate calculation, power load rate, reliability, large load rate, timing query power factor, active power, reactive power, draw each phase voltage, current, power factor, print comprehensive analysis and statistical report.
