implementation of intelligent tracking compensation, its reasonable structure, advanced technology, widely used in Low-voltage power grid, improve power factor, reduce reactive power loss, improve power supply quality, is a new generation of energy-saving products. Dedicated to the 130-600KVA three-phase transformer reactive power compensation.
The device accords with standards IEC439-1 and GB7251.1.
Use environmental conditions
1) Altitude: W 2000m;
2) Ambient temperature: -20 ºC ~ +45 ºC;
3) Relative humidity: W 90% at 20 ºC;
4) Installation environment: no harmful gases and steam, no conductive or explosive dust and serious mold.
Distribution Network Detection Function
1) Real time measurement and hourly recording of three-phase voltage, current, frequency, active power, reactive power, power factor, active energy, reactive energy on the low-voltage side of transformers: total distortion rate of voltage and current and 2-25th harmonic content;
2) Equipped with RS-232 and RS-485 interfaces, it can record data from handheld computers and also achieve wireless meter reading, device testing, parameter setting, real-time measurement data, and record data reading through remote communication functions;
3) Data analysis function: It can analyze, process, and perform statistical queries on operational load data; Comprehensive analysis of power supply quality,calculation of voltage qualification rate, power supply load rate, reliability rate, and maximum load rate; Query power factor, active power, and reactive power in different time periods; Draw curves of voltage,current,power factor,etc.for each phase:print comprehensive analysis and statistical reports.
