Nowadays, the national grid and Southern Power Grid pay more and more attention to the solution of single-phase grounding fault. The device to solve single-phase ground fault in the market is the small current grounding line selection device. However, due to the continuous expansion of the power grid, the complex and diverse grounding modes, the steady-state algorithm is not enough to accurately select the line, which leads to the reduction of the accuracy of the common small current grounding line selection device.

 Industrial computer small current grounding line selection device is a series of products newly developed and produced by our company. The line selection accuracy of this product is higher than that of ordinary small current grounding line selection, and it can solve single-phase grounding fault, which needs to be widely recognized by the market.

The small current grounding line selection device developed by our company has the function of rotary cutting. This function is not available in the common low current grounding line selection in the market. The function of turn off is to start the function of turn off according to the setting after the trip failure of the device line selection, and act one by one in sequence until the fault line is selected and removed, which is to ensure the accuracy of line selection again.

 It should be noted that the wheel cutting function of the IPC grounding line selection device is started after the failure of line selection function. If the line selection is correct, the wheel cutting function will not be activated. The function of wheel cutting is to ensure the accuracy of line selection. This is one of the differences between the small current grounding line selection device of industrial computer and ordinary small current grounding line selection device. This is also one of the reasons for the high accuracy of the line selection device for small current grounding.
