Power Quality Meter Three Phase Power Quality Analyzer Current Clamp 1.0A~1000A

Introduction:

• VTSYIQI Three Phase Power Quality Analyzer, also known as power quality analyzer, power parameter tester and harmonic analyzer, which is a high-precision comprehensive testing instrument designed specifically for on-site testing of three-phase power quality. 
• The instrument has the characteristics of intelligence, comprehensive function, simple human-machine operation and bilingual operation interface in Chinese and English. 
• The instrument adopt with 5-inch true-color touch screen, which is small in size, lightweight, and convenient to carry. Multiple current clamps can be optionally equipped. 
• The instrument can simultaneously measure 4 channels current (ABC three-phase and neutral line currents), 3 channels voltage, three-phase imbalance, active power, reactive power, apparent power, harmonic ratio, total harmonic distortion, etc.
• Display real-time waveform and phasor diagram of current and voltage; dynamic capture of instantaneous changes in voltage and current, monitoring of starting current, monitoring of various power parameters and generating alarm lists, long-term recording of test data and generation of trend curves, and other functions. 
• Suitable for power, petrochemical, metallurgical, railway, industrial and mining enterprises, scientific research institutions, metrology departments, etc.
• VTSYIQI Three Phase Power Quality Analyzer adopt with 5 inch true-color touch screen to display, which uses different colors to distinguish the parameter, waveform, phasor, and harmonic ratio of each phase, allowing user to more efficiently and intuitively understand the status of power grid parameter. 
• Upload stored data to the computer through USB communication interface and upper computer software to continue data analysis.

Main Function:

• Real time waveform display (3 channels voltage/4 channels current).
• True effective value of voltage and current.
• Phasor diagram display.
• Measurement of harmonics in each phase, up to 50 harmonics.
• The bar chart displays the harmonic content of each phase's current and voltage.
• Total harmonic distortion (THD).
• The active/reactive/apparent power value and total value of each phase.
• Voltage, current and power trend chart.
• The active/reactive/apparent power value and total value of each phase.
• Measurement of three-phase imbalance (voltage and current).
• Record waveform and parameter.
• Screenshot save.
• Touch screen operation.
• Short term voltage flicker.
• Starting current and surge current monitoring.
• USB communication interface and computer upper communication.
• The wiring method of the instrument and the type of power grid can be set.
• Different current clamp and voltage test ratio can be set.

Features:
