High-Precision RAVS Device for Online Voltage Monitoring - China Suppliers & Factory Solutions
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.

Frequently Asked Questions (FAQ)
How does the device achieve precise time synchronization?
The device supports Beidou and GPS timing. It can be connected to a separate external time synchronization device or share the clock with your original system.
What kinds of voltage events trigger automatic recording?
The device automatically triggers recording for voltage flicker, sag, oscillation, deviation, surge, single-phase grounding, and phase-to-phase short circuits when values exceed the set thresholds.
What is the duration and range of the fault recording?
When a threshold is crossed, the system initiates a panoramic recording capturing data from -1 second prior to the event up to +30 seconds post-event.
Do I need to install separate monitors for routine power quality checks?
No, the device has built-in routine monitoring capabilities for voltage fluctuations, load current, power analysis, THD, and imbalance, eliminating the need for extra monitors.
