- RDCR5000
1. RDCR5000 Power Quality Analyzer is a comprehensive test instrument and specially designed for field test of three phases, multi-functional and intelligent, concise man-machine operation.
2. Digital Power Quality Analyzer is easy to use, large LCD screen display, high resolution, interface in both Chinese and English, shock-proof shell structure, and so on.
3. It can simultaneously measure the 4-channel current (ABC three phase and neutral wire current), 4-channel voltage (ABC three-phase voltage and neutral line voltage to ground), the peak value of current voltage, maximum/minimum value over a period, three-phase imbalance factor, short-time voltage flicker, transformer K factor, active power, reactive power, apparent power, power factor, and displacement power factor, active power, reactive power, apparent power, total harmonic distortion, and harmonic, etc.
4. The Digital Power Quality Analyzer can display real-time waveforms, harmonic ratio bar charts of current voltage, and dynamically capture instantaneous changes in voltage current. It can monitor starting current, power parameters, and generate an alarm list. It also generates trend charts for long-term recording of test data.
Features
The analyzer adopt DSP + ARM double processor architecture, DSP is use for data collection and the processing of algorithm, the ARM is use for the communication protocol and the man-machine interface processing;
Analog signal acquisition is by 2 pieces AD7655 of ADI company. Resolution for AD7655 is 16 bit and it is 4 channel synchronous sampling. The highest sampling rate can reach 1 MSPS, to ensure the accuracy of the channel and the information integrity, and wouldn’t miss any transient changes in the grid, can more accurate to detect the transient waveform rising and dropping drastically, and waveform instantaneous interrupt;
DSP working frequency is over 200 MHZ, to be able to timely monitoring of the power grid and dynamically adjust the sampling frequency to realize synchronization of power frequency and sampling frequency;
Using a 5.6 -inch LCD color screen display, a resolution of 640 dots x 480 dots, with different display color difference between the parameters of phase, waveform, vector diagram, harmonic ratio, the user can be more efficient and more intuitive understand the state of power grid parameters.
Built-in flash memory can store 60 group of screenshots at the same time, 150 groups of capture transient voltage/current waveform figure, and 12800 groups of alarm list. Starting current detection model can continuously capture starting current waveform for 100 s.
Built-in 2G memory card to store the trend curve record, simultaneous recording 20 parameters (can choose according to need) collect data for once every five seconds, trend curve records can be stored for 300 days.
