    Digital Power Quality Analyzer

    1. RDCR5000 Power Quality Analyzer is a comprehensive test instrument and specially designed for field test of three phases, multi-functional and intelligent, concise man-machine operation. 2. Digital Power Quality Analyzer is easy to use, large LCD screen display, high resolution, interface in both Chinese and English, shock-proof shell structure, and so on. 3. It can simultaneously measure the 4-channel current (ABC three phase and neutral wire current), 4-channel voltage (ABC three-phase voltage and neutral line voltage to ground), the peak value of current voltage, maximum/minimum value over a period, three-phase imbalance factor, short-time voltage flicker, transformer K factor, active power, reactive power, apparent power, power factor, and displacement power factor, active power, reactive power, apparent power, total harmonic distortion, and harmonic, etc. 4. The Digital Power Quality Analyzer can display real-time waveforms, harmonic ratio bar charts of current voltage, and dynamically capture instantaneous changes in voltage current. It can monitor starting current, power parameters, and generate an alarm list. It also generates trend charts for long-term recording of test data.

    The Nonlinear Challenges in Power System Components

    In the power supply system, nonlinear issues arise from various elements. For instance, harmonics are generated during the normal operation of generators. Transformers within the grid also contribute to harmonic production. Additionally, DC transmission introduces harmonics, and high-voltage transmission lines can amplify these harmonics. The installation of parallel capacitors in substations is another factor that can lead to the emergence of harmonics. Among these, DC transmission is currently a major source of harmonics in power systems.

    What You Don't Know About Power Quality Governance

    On the one hand, in addition to the problem of low power factor, a variety of converters and other power electronic devices are increasingly widely used for the introduction of a large number of harmonics into the power grid; on the other hand, a large number of precision instruments are very susceptible to the impact of power harmonics, the power quality of the requirements of more and more high. It is imperative to actively and effectively manage power quality on the user side.
