  Abstract: Ground fault protection for electrical circuits, equipment and electrical fire accidents caused by ground fault currents are increasingly becoming a daily necessity. For the main energy-consuming nodes on the user side, a residual current relay is designed and installed to monitor the residual current status of each energy-using circuit in real time. Through real-time monitoring of energy use and related power parameters, the safety, reliability and maintenance efficiency of energy use are improved, the labor cost of maintenance is reduced, and the unattended monitoring of residual current is realized. Through the real-time monitoring of energy use, data collection and alarm, the residual current in the power distribution system is monitored, and the ground fault protection of the user's electrical circuit is provided to prevent fire accidents and personal electric shock accidents caused by residual current. Here is a brief introduction to the application of our company's ASJ earth leakage relay in the Philippine mine.

。

  The mine factory is located in the Philippines, because the current is very big, electricity supply for mine is special , customers hope that through in the power distribution ark installation of residual current relay to residual current monitoring line, and hope that can be displayed on the display panel real-time monitoring of residual current value rather than setting the ratio of residual current value, the ratio can reach 80% when the residual current relay immediately report . Acrel ASJ10-LD1A with residual current transformer, successfully solve the customer's on-site residual current monitoring requirements. Due to the large current on site, we have communicated for many times on the selection of residual current transformer, and selected the most appropriate residual current transformer for the customer based on copper bar and current specifications.
