ETCR EM5000 Power Quality Analyzer, also known as power parameter tester and harmonic analyzer, which is a multifunctional and intelligent integrated test instrument designed for on field testing of three-phase power parameter. Can simultaneously measure 4 channel currents (ABC three-phase and neutral line current), 4 channel voltages (ABC three-phase voltage and neutral line grounding voltage), peak value of current and voltage, maximum and minimum value over a period of time, three-phase imbalance, short-term voltage flicker, transformer K-factor, active power, reactive power, apparent power, power factor, displacement power factor, active energy, reactive energy, apparent energy, harmonic ratio, total harmonic distortion, etc; Display real-time waveform of current and voltage, phasor diagram and harmonic ratio bar chart; Dynamic capture instantaneous changes of voltage and current, monitoring starting current, monitoring various power parameters and generating alarm lists, long-term recording of test data and generation of trend graphs and other functions. Suitable for power, petrochemical, metallurgical, railway, industrial and mining enterprises, scientific research institutions, metrology departments, etc.

ETCR EM5000 Power Quality Analyzer adopt with DSP+ARM dual processor architecture, DSP is responsible for data acquisition and algorithm processing, ARM is responsible for communication protocol and human-machine interface processing; The analog signal acquisition is completed using two ADI company resolution 16 bit 4-channel synchronous sampling AD7655 chips, achieving a maximum sampling rate of 1MSPS, ensuring the accuracy and information integrity of the channels, and not missing any transient changes in the power grid, making the detection of transient waveforms, sudden rise and fall, instantaneous interruptions, etc. more accurate; DSP operating frequency of more than 200MHz , Can monitor the power grid in a timely manner and dynamically adjust the sampling frequency to achieve synchronization of power frequency and sampling frequency. Using 5.6 inch LCD color screen display with resolution of 640dots × 480dots, displaying parameters, waveform diagrams, phasor diagrams and harmonic ratio diagrams of each phase with different colors, which enable users to more efficiently and intuitively understand the status of power grid parameters. The built-in SD flash memory can simultaneously store 60 sets of screenshots, 150 sets of transient voltage/current capture waveforms, 12800 sets of alarm logs, and the startup current detection mode can continuously capture the startup current waveform for 100 seconds. The built-in 2G memory card is used to store long-term trend curve records, while also recording 20 electricity parameters (optional). It can be collected and recorded once every 1 minute, and can record and store trend curve records for up to 300 days. Upload stored data to the computer through USB communication interface and upper computer software to continue data analysis.
