Power quality analyzers identify issues with power quality which typically manifest as dips, swells, harmonic distortion, unbalance, flicker, and transients. Power quality determines the suitability of electrical power to drive motors, machines and other end user devices. Poor power quality affects the ability of these devices to operate properly which may cause malfunctions, premature failure or may cause them to not work at all. Most power quality analyzers monitor total harmonic distortion, phase angle, power factor, balance and more to get a complete picture of the system.
Like any troubleshooting task, you want the right tools to get the job done. When it comes to power quality, finding, troubleshooting and removing problems with dips and swells, harmonics, imbalance, along with other power quality problems can be difficult. Capturing the information needed to analyze and diagnose is the initial step in solving these power quality issues. Weshine invented the VS-X710 is an ideal choice when continuous monitoring of a three phase system is required. It provides metering for current, voltage, real and reactive power, energy use, cost of power, power factor and frequency. Weshine Power Quality Analyzers can help you identify and trace anomalies and harmonic distortion problems - even the ones which are the most difficult to find.
The Handheld Power Quality Analyzer invented by Weshine is a high-performance multi-function power quality analyzer. Adopt DSP+ARM+CPLD core, 3.2" large-screen LCD (320×240 dot matrix) display, making the structure more compact, more powerful and more convenient to display. Background management analysis software, rich in functions and easy to operate.
TYPICAL APPLICATION
1. Measure and analyze the AC power quality supplied by the public power grid to the user end, and its measurement and analysis: frequency deviation, voltage deviation, voltage fluctuation and flicker, three-phase voltage allowable unbalance, power grid harmonics.
2. Apply wavelet transform to measure and analyze the harmonics of non-stationary time-varying signals.
3. Measure and analyze the power quality of various electrical equipment to the public grid under different operating states.
4. Load fluctuation monitoring: regularly record and store the trend of changes in power parameters such as voltage, current, active power, reactive power, apparent power, frequency, and phase.
5. Dynamic monitoring of power equipment adjustment and operation process to help users solve problems in the process of power equipment adjustment and commissioning.
6. Test and analyze the failure causes such as circuit breaker action, transformer overheating, motor burnout, and automatic device malfunction in the power system.
7. Test and analyze the dynamic parameters of reactive power compensation and filtering devices in the power system and make quantitative evaluations of their functions and technical indicators.
8. The characteristics of portable, multi-parameter, large capacity, high precision and the application of modern signal analysis theory make the power quality analyzer can be widely used in power transmission and distribution, power electronics, motor driving and other fields.
