Feature of Remote Overhead Line Fault Indicator
- Short Circuit: Indicated by a red mechanical flag and three ultra-bright blinking LEDs.
- Earth-fault: Indicated by a red mechanical flag and three ultra-bright blinking LEDs.
- Low Battery Warning: Indicated by red mechanical flag
- Parameter Adjusted: The parameters can be read and adjusted by the bidirectional wireless tool.
- Remote Transmission: DCU can transmit data to the SCADA system.
- Power Supply: The indicator can take power from overhead lines, with a lithium battery as backup. The DCU can take power from solar energy with lithium battery backup.
