Product Detail

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).
9	Routine power quality monitoring	Voltage fluctuation, load current, power analysis, THD monitoring, imbalance monitoring, etc. No need to install other power quality monitors.
