RAVS: Advanced China Factory Supplier for Real-Time High-Frequency Power Supply Voltage Monitoring Solutions
Functional Features
Beidou/GPS timing
01
Can be connected to a separate external time synchronization device or shared with the original system clock.
Voltage flicker
02
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).
Voltage sag
03
If the voltage of any phase is lower than the set threshold, immediately start recording (-1~+30s).
Voltage oscillation
04
Oscillation is difficult to prevent and poses serious harm. When the oscillation amplitude exceeds the set threshold, immediately start recording (-1~+30s).
Voltage deviation
05
The transient voltage waveform contains a DC component, and when the amplitude exceeds the set threshold, the recording is immediately initiated (-1~+30s).
Voltage surge
06
External surge, power transmission, protrusion, sudden load rejection, etc., exceeding the set threshold, immediately start recording (-1~+30s).
Voltage grounding
07
When a single-phase grounding fault occurs in the system, accurately identify the fault and its occurrence time, and immediately start recording (-1~+30s).
Voltage short circuit
08
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).
