1.High-speed Digital Sampling Technology



 
The sampling frequency of current and electric field can

reach 4KHz.
 It will trigger high-speed wave recording of geoelectric field

intelligently, and accurately capture instantaneous transient

recorded waveform signals of small-current earth faults.

 



2.High-precision Three-phase Synchronous Timing
 
 

Based on GPS clock signals, Four-Faith unique algorithms are used to achieve high synchronization

performance.
 When three-phase wireless synchronization timing is performed, the accuracy is less than 100μs, and the

three-phase phase angle error is not more than 1.8°.
 

 


 













3.Ultra Low Power Consumption
 
 
 
After several rounds of optimization by Four-Faith software and hardware

engineers, the transient wave recording fault indicator adopts low-power

consumption CPU and industrial-grade wireless communication modules to

realize extremely low-power consumption and real-time two-way communication.

 
 


4.Accurate Measurement and Strong Anti-Interference Ability
 
 
Innovative Split-core Rogowski Coil electronic current transformer, line current measurement accuracy ±1%.
Optimize the design of electric field sensor, which is not affected by the loop line of the same pole frame, and accurately identify the voltage drop and power failure.
Based on GPS clock signals, Four-Faith unique algorithms are used to achieve high synchronization

performance.
 When three-phase wireless synchronization timing is performed, the accuracy is less than 100μs, and the

three-phase phase angle error is not more than 1.8°.
