RAVS for Transient Fault in Power Supply
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~+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 ） |
| 9 | Routine power quality monitoring | Voltage fluctuation, load current, power analysis, THD monitoring, imbalance monitoring, etc. No need to install other power quality monitors. |
| 10 | Main spec | Sampling frequency 100kHz; monitor 0-63 harmonics, inter harmonics, and higher harmonics; 4G memory, 64G solid-state drive; LCD high brightness TFT LCD touch screen; 10 inches; Resolution 800 × 600; one × RS-232/485, 1 × RS232, 4 × USB2.0, 1 × VGA, 1 × GigaLAN |
