High-Precision RAVS Monitoring Device for Transient Faults in Power Supply - China Suppliers & Factory Offer

Introducing RAVS, an advanced monitoring device meticulously engineered for China's industrial needs, specializing in the online long-term high-frequency recording of sudden voltage changes. As a leading solution among suppliers and factories, RAVS offers real-time monitoring of system voltage, effectively tracking voltage fluctuations and ensuring optimal power quality. With its high accuracy, precision, rapid response, and exceptional stability, RAVS sets the standard for voltage monitoring devices.

Unlike commonly used waveform recorders or power quality monitoring equipment that struggle with capturing short-duration voltage fluctuations, RAVS excels in accurately monitoring and recording prolonged variations in system voltage. It conducts real-time analysis of a range of voltage issues, including flicker, oscillation, deviation, surges, grounding, and short circuits. With its comprehensive recorded analysis, RAVS delivers precise quantitative parameters and practical solutions for fault warnings, analysis, and resolution. Additionally, RAVS can perform real-time online monitoring of conventional power quality metrics such as voltage, current, power, Total Harmonic Distortion (THD), and imbalance, making it an indispensable tool for factories and suppliers across China.

Functional Features

No.	Feature	Description
1	Beidou/GPS timing	Can be connected to a separate external time synchronization device or shared with the original system clock.
2	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).
3	Voltage sag	If the voltage of any phase is lower than the set threshold, immediately start recording (-1~+30s).
4	Voltage oscillation	Oscillation is difficult to prevent and poses serious harm. When the oscillation amplitude exceeds the set threshold, immediately start recording (-1~+30s).
5	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).
6	Voltage surge	External surge, power transmission, protrusion, sudden load rejection, etc., exceeding the set threshold, immediately start recording (-1~+30s).
7	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).
8	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).
