EITAI5000 Power Quality Analyzer is a comprehensive testing instrument designed for on-site testing, featuring three-phase, multi-functionality, intelligence, and user-friendly operation. It boasts a simple operation, a large LCD color display with high resolution, a bilingual interface in Chinese and English, and a vibration-resistant structural casing. It can simultaneously measure 4 channels of current (ABC three-phase and neutral line current), 4 channels of voltage (ABC three-phase voltage and neutral line-to-ground voltage), peak values of current and voltage, maximum and minimum values within a period, 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. It displays real-time waveforms, phasor diagrams, and harmonic ratio bar charts of current and voltage; dynamically captures instantaneous changes in voltage and current, monitors start-up current, monitors various power parameters and generates alarm lists, records test data for a long time, and generates trend curve graphs, etc.
The waveform mode is one of the main functions of the EITAI5000 Power Quality Analyzer, displaying voltage waveforms, current waveforms, which can be displayed separately by phase or by line, with true RMS display, total harmonic distortion rate display (THD), crest factor display (CF), maximum and minimum values, and average values of voltage and current (Max/Min), simultaneous display of various test values (RMS/DC/THD/DF/CF), and phasor diagram display, totaling six display modes.
1.True RMS Display (RMS)
Displays the waveform and true RMS value of the measured signal during a certain period of time, and can display the waveform and true RMS value of current and voltage separately by different phase or line.
2.Total Harmonic Distortion Rate Display (THD)
Displays the waveform and total harmonic distortion rate of the measured signal during a certain period of time, and can display the waveform and total harmonic distortion rate of current and voltage separately by different phase or line.
3.Crest Factor Display (CF)
Displays the waveform and crest factor of the measured signal during a certain period of time, and can display the waveform and crest factor of current and voltage separately by different phase or line.
4.Maximum and Minimum Values of Voltage and Current (Max/Min)
Displays the RMS value, maximum value, minimum value, positive peak maximum value, and negative peak minimum value of voltage and current.=
5.Simultaneous Display of Various Test Values (RMS/DC/THD/DF/CF)
Displays all voltage and current measurement values (RMS, DC, THD, DF, CF, PST, KF).
6.Phasor Diagram Display
Displays the absolute value, phase, and imbalance of voltage or current at the fundamental frequency.
