China RAVS Transient Fault Monitoring Device - Suppliers & Factory for High-Frequency Voltage Recording
Functional Features
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 to +30s).
3
Voltage Sag
If the voltage of any phase is lower than the set threshold, immediately start recording (-1 to +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 to +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 to +30s).
6
Voltage Surge
External surge, power transmission, protrusion, sudden load rejection, etc., exceeding the set threshold, immediately start recording (-1 to +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 to +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 to +30s).
9
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
What time synchronization methods does the system support?
The system supports Beidou and GPS timing. It can be connected to a separate external time synchronization device or shared with the original system clock.
How does the device handle voltage anomalies like sags, surges, or flickers?
When a voltage anomaly (such as sag, surge, flicker, oscillation, deviation, grounding, or short circuit) exceeds the set threshold, the system immediately initiates recording from -1 second before the event up to +30 seconds after.
Does this system require additional power quality monitoring devices?
No, the system includes built-in routine power quality monitoring (voltage fluctuation, load current, power analysis, THD monitoring, and imbalance monitoring), eliminating the need for external monitors.
