Features

 

1. Local communication:

- The acquisition unit and the remote transmission collection unit on the line can communicate wirelessly, and the communication distance is more than 100 meters.

 

2.Ways to detect short circuit faults:

- The over-current catastrophe method: automatically tracks the load current without setting the operation parameters.


- The over-flow break method: can prevent the misoperation of reclosing inrush current and the sudden change of small current.

 

3. Detect grounding fault:

- Detect transient current at the moment of grounding and identify grounding fault.

 

4 Double CT structure:

- The electronic current transformer is used for measurement; the electromagnetic transformer is used for power collection, which increases the measurement accuracy and operation stability.

 

5. Three-phase time recording function:

- The synchronization progress of three-phase recording ≤50uS.
 

6. Zero-sequence current synthesis:

- The zero sequence current criterion is introduced into the grounding detection criterion to increase the accuracy of grounding detection.

 

7. Low battery voltage alarm.

 

8. Full-function 4A operation when battery free:

- For the data acquisition unit with battery failure, as long as the line current is greater than 4A, data acquisition unit will run with full function.

 

9. Bulk backup capacitance:

- When battery is full, the backup capacitance could maintain the full function data acquisition unit for 12 hours.

 

10. Auto-reset:
- 1min~48h optional for factory-setting, or intelligent restore (restore immediately after power supply resumed). 

 

11. Hot-line handling:

- Not requiring special tools, standard insulated operating rods.

 

12. Display mode:

- LED light, flashing light.

 

Situation

 

Applicable to the power distribution automation renovation of the overhead line of 10kV distribution network, it can realize the function of judging short circuit and grounding fault, and has the function of recording wave, to realize fault backtracking and support big data analysis.
