High-Frequency Voltage Monitoring Device RAVS - Reliable China Suppliers & Factory for Power Quality Solutions

RAVS is an advanced monitoring device engineered for online, long-term, and high-frequency recording of sudden voltage changes in electrical systems. Designed by a leading China supplier, RAVS excels in providing real-time monitoring of system voltage fluctuations and power quality. Its features include exceptional accuracy, precision, rapid response time, and remarkable stability, making it a preferred choice among industry professionals, Unlike typical waveform recorders or power quality monitoring devices available in the market, RAVS effectively captures and analyzes short-duration voltage fluctuations. It comprehensively tracks and records voltage changes over extended periods, identifying critical voltage issues such as flicker, oscillation, deviation, surges, grounding, and short circuits. By delivering precise quantitative parameters based on recorded data, RAVS aids in fault warning, analysis, and resolution, Additionally, RAVS offers real-time online monitoring of essential power quality metrics, including system voltage, current, power, Total Harmonic Distortion (THD), and imbalance. As a reliable factory source in the industry, RAVS ensures that users gain insights necessary for maintaining optimal power quality and system performance

    Functional Features
    01 Beidou/GPS timing
    Can be connected to a separate external time synchronization device or shared with the original system clock.
    02 Voltage flicker
    If the difference between the maximum peak values of the two adjacent wave heads of the voltage waveform exceeds the set threshold, immediately start recording (-1~+30s).
    03 Voltage sag
    If the voltage of any phase is lower than the set threshold, immediately start recording (-1~+30s).
    04 Voltage oscillation
    Oscillation is difficult to prevent and poses serious harm. When the oscillation amplitude exceeds the set threshold, immediately start recording (-1~+30s).
    05 Voltage deviation
    The transient voltage waveform contains a DC component, and when the amplitude exceeds the set threshold, the recording is immediately initiated (-1~+30s).
    06 Voltage surge
    External surge, power transmission, protrusion, sudden load rejection, etc., exceeding the set threshold, immediately start recording (-1~+30s).
    07 Voltage grounding
    When a single-phase grounding fault occurs in the system, accurately identify the fault and its occurrence time, and immediately start recording (-1~+30s).
    08 Voltage short circuit
    When a phase to phase short circuit fault occurs in the system, accurately identify the fault and its occurrence time, and immediately start recording (-1~+30s).
    09 Routine power quality monitoring
    Voltage fluctuation, load current, power analysis, THD monitoring, imbalance monitoring, etc. No need to install other power quality monitors.
