With the advancement of power detection and communication technology, as well as the development of big data, Four-Faith intelligent LED fault indicator can work under 3A current, perform fast fault detection within 20ms, and support power line clamping, through 3 different color LEDs The light change prompts the fault information, which is clear in the daytime of 100m and the night of 500m, which greatly shortens the time and scope of fault finding. LED Fault indicator is our unremitting pursuit to help you quickly restore the power supply. JYZ-HW Data Concentrator Unit/DCU for Overhead Line Remote Fault Indicators is used for receiving the data from fault indicator units and transmit the data to SCADA system via 2G/3G/4G networks The Data Concentrator Unit/DCU is usually installed on the pole. It supports to connect with maximum 9pcs indicator units. The communication between DCU and indicator unit is via RF2.4GHz. When there’s fault happen, indicator unit will send the fault message immediately to DCU, and DCU upload to SCADA system for notifications.
