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.
