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 residual current relay in the water terrace house project around the island Maldives.

1.項(xiàng)目概述  Project Overview

The water townhouses around the island in the Maldives are mainly used to receive tourists from all over the world. The application site frequency is 50 Hz and the voltage is 220V TT or TN system power distribution lines. The customer hopes to monitor the residual current of the line by installing a residual current relay in the distribution cabinet of the water row house, and hopes that the ratio of the real-time monitored residual current value to the set residual current value can be displayed on the display panel, when the ratio reaches 80%, the residual current relay can alarm immediately. Acrel ASJ10-LD1A cooperates with the residual current transformer, Successfully solved the customer's on-site residual current monitoring needs.
