Product Introduction:
The ZXDN-3700 Power Quality Analyzer is a multifunctional testing instrument integrating power quality analysis, electrical parameter testing, and power vector analysis. Designed for 50Hz/60Hz power frequency systems, it records and analyzes all key power quality parameters, including harmonics, voltage, current, frequency, fluctuations, flicker, voltage swells and sags, power, and three-phase unbalance. Equipped with advanced power quality measurement capabilities, it also features professional PC analysis software for secondary diagnostics, providing users with precise power fault analysis.
The device utilizes high-precision, highly linear voltage transformers and clamp-type current transformers to ensure exceptional measurement accuracy across all parameters, while simplifying on-site wiring. Its imported large-color LCD touchscreen offers an intuitive Chinese-language interface with real-time prompts, multi-parameter displays, and vector diagrams for reliable circuit verification.
With built-in large-capacity non-volatile memory, the instrument securely stores massive field test data, delivering dependable on-site information for in-depth software analysis.

3. It can measure the voltage harmonic and 2-64th current harmonic content
4. It can measure the 0.5-31.5 Inter-harmonic content of voltage and current
5. It can measure the total harmonic distortion rate of voltage and current
6. Can measure and short-term flicker (Pst), long-term flicker (Plt), voltage fluctuation
7. It can measure positive sequence voltage, negative sequence voltage, zero sequence voltage, voltage unbalance
8. It can measure positive sequence current, negative sequence current, zero sequence current, current unbalance
9. It has the function of measuring transient parameters and the function of recording voltage swells and drops. At the same time, the recording function is automatically started to record the occurrence time of the event and the actual waveforms of the five cycles before and after the occurrence.
10. It has an oscilloscope function, which can display the size and distortion of voltage and current in real-time waveforms, and can zoom in and out of the voltage and current waveforms on the instrument
11. It has a hexagonal diagram display function, which can perform vector analysis of the metering circuit and the protection device circuit, and check the wrong wiring of the metering device; in the three-phase three-wire connection mode, it can automatically judge 48 wiring methods; the automatic calculation function of the supplementary power is convenient to use. The personnel calculate the supplementary power for users with wiring problems.
12. Optional large clamp can be used to measure the transformation ratio and angle difference of low-voltage current transformers
